Men's Catalyst Softshell Pant
2 Layer Silent Softshell

From the treestand to the tundra, the Men's Catalyst Softshell Pant changes the paradigm of technical hunting softshell pants. Silent, breathable, insulating, and engineered to stretch and move with you, the Catalyst changes what is possible in a softshell pant. The revolutionary, 2-layer construction creates a jacket that is warm and breathable while also being lightweight and completely silent.


Interior 37.5 fleece lining works to optimize your body temperature while the brushed, durable exterior is ultra-silent while fending off moisture through our advanced DWR.


The result is an ultra-versatile pant that performs as well in the stand as it does in the backcountry. Whether you are looking for silent warmth sitting for whitetails during the rut or hoofing it through knee-deep snow on the trail of late season elk, the Catalyst softshell system will help you get it done.


The Catalyst is also available in a Men's Jacket.


*More inventory expected in early summer.

Excellent hunting pant 12/6/2018

I bought these pants to replace my Scent Blocker Outfitter pants. By the time I would get to my tree stand, my legs would be sweating horribly. If I had my phone in my pocket, the screen would be covered in moisture. I knew I wanted a good pair of bow hunting pants from temps of 60° to 35°. These pants did not let me down. No more sweating walking to my stand. They do get a little cold for temps under 35°

I shot my deer this year and tracked it thru thick golden rod field mixed with thorns. I went through some thorns and got upset I might have put a hole in them. After I recovered my deer and went back to camp, I did a thorough inspection and there wasn't any tears or rips. The material is very flexible and durable.

The suspenders are an excellent compliment to the pants. I really enjoyed these pants this hunting season.

Good pants, but can we get talls please? 11/19/2018

Enjoyed the texture and warmth, nice quiet well made pant. Good product as you transition out of Idaho September Elk and into the later general season hunts. My only gripe is the fit, for $230 lets get some Talls in the mix. I'm 6'1, 190, typically wear a 33X34 I bought the larges on recommendation from the staff and the pants are baggy in the waist and a bit short on the boot.

Highly functional and versatile 11/18/2018

I've tried them all. Different materials, brands, patterns, fits, etc. Going forward I don't think I'll be buying anything else. After beating through about 800m of muskeg and dense brush I remained relatively dry and warm. The flexibility of these pants when navigating tough terrain are unparalleled by anything I've worn before. I never felt restricted when having to climb around deadfall or hike up steep terrain. Excellent construction. Awesome fit.

new all round pant 11/15/2018

Love these pants. They shed water, snow, and block the wind. Pretty quite have no problem slipping though the woods. Ive busted a little bit of brush with them, haven't had any problems. I like the side pockets both sides have dual pockets one zippered one open. The pockets are easily accessible even with gloves on. Worn them whitetail hunting (stand and stalk),turkey hunting, water fowl, pretty much my go to pant.

Overall a very good midseason pant. 11/14/2018

I have been able to try these in the field under a range of temperatures and conditions and have been pleased with their performance. I have worn them primarily treestand hunting. The temperature range I have tried them in so far was from the 70s all the way down to the upper 20s with a baselayer and that's about their limit for my comfort level. One day maybe First Lite will get a Woodbury pant made(hint, hint). The side thigh pockets are great, love their design. I dislike the zippered hip pockets. The big thing I don't like about them is the orientation on the pant being perfectly vertical. It makes access difficult, especially when sitting. Otherwise the fabric is terrific and very quiet, DWR works, and the wind resistance is adequate for most circumstances. They are a very versatile pant I am glad I purchased.


How it fits
I wear 32/32 and the fit was good. I have been wearing the Med-Tall in most of the other pants where it's offered and was concerned these might not be long enough, but they fit without issue.

Great!! 11/12/2018

These are the most comfortable mid weight hunting pants I have ever worn, PERIOD! They worked as advertised hiking up and down the mountains in Colorado chasing elk. If I could make one change it would be to add a full length zipper along the legs of the pants for extra ventilation and ease of removal, if you did that these would be the perfect hunting pants.

Really Comfy Pants 11/12/2018

Originally thought inseam was short (my bad First Lite), but seems like they run roughly 33-34".

This is how i prefer my outdoor/hunting pants. So when i sit down and the pant rides up a bit, the leg cuffs still cover over my boots. I hate it when pant cuffs ride up and go over the rear boot loops.

Material seems durable, walked through some thorny tall grass and no loose threads after. A little warm for 75*F and up, but it can work up to about 85*F (I was wearing a thin wool base layer).

I did not wear these with the suspenders, but i tried it on and its also very comfy.

Tried to purchase another pair in Dry Earth but it's all sold out. Love the Cipher pattern.


How it fits
I'm 5'8" (around 5'9" with boots)
I normally wear 30x32+. Skinny and long body frame and pretty flat bottom. These fit great for my body frame, closer to athletic fit. Inseam taper is perfect and fits over my boots perfectly.
Inseam length is just about right (estimating it's about 33"34" inseam for the Small).

Great pants 11/10/2018

Not too hot in early season and very comfy and durable. I felt mine ran a tad large but it leaves perfect room for thermal underware. They are my favorite pants and when I put them under the discontinued "Noth Branch" pants I'm comfortable down to 14° F so far.


How it fits
There is enough room for thermal underware.

Great Pants 11/9/2018

These are incredible pants. Super quite when walking to my tree stands. I typically wear the furnace set underneath with temps between 30-45 degrees. They have a tapered fit and feel less bulky than other pants I own. Very flexible and comfortable and warm. They are effective blocking wind. Perfect mid to late season pant.


How it fits
Tapered fit go up a size if you plan on using two base layers underneath.

overall very pleased. 11/8/2018

have put a good amount of hunts in these pants now so I thought id give my opinion. Overall size and fit is very good, ordered the size I wear in most pants and the waist and length were just right. With they came in TALL lengths but not a big deal.

My main issue is pocket placement and size. the waist pockets are SUPER short and zipper is not very long. I have average to slightly above average hand size and I can barely fit my whole hand into the pocket without the zipper scratching me pretty good. Then the actual pocket size is pretty small, you are not gonna fit much in there. Just cant figure out how they thought the zipper length was enough.

The thigh pockets are very good and decent size, however I really really wish they would add a side entry zipper like on the corrugate pants. sitting in the turkey woods or in a tree stand that side entry pocket makes like much much easier.

finish is awesome however I wouldnt say they are super warm. I was hoping for a real mid-weight pant but they are a bit below that and on colder days you can feel it.

Having said that I really do like them and they will for sure be in my closet for a long time. with some minor modifications these could be a 5* no doubt and knowing FL's history they will make changes were needed.

Late Season Elk - Dead fall & burns at 7200 ft, 8-12 inches of snow with 50 mph gusts of wind... EXCELLENT! 11/8/2018

After months of waiting, I finally had the opportunity to put the Catalyst Softshell Pant to the test during my late season rifle hunt for Elk. We spent 5 days hiking with 8-10 inches of snow at 7200 feet, crawling over/under deadfall and the thickest timber/thickets that we could find. The pants not only kept me warm, but handled the obstacles without a snag. You will be hard pressed to find a better combination of the pants and the brambler gaiters.


How it fits
As for fit, I am 5'7" and weigh approx. 168 lbs. I bought a medium and it was the perfect size. I like the straight leg feel of the pant, it fit's over my Crispi Idaho boots perfectly. Due to the pajama type feel/stretch, I didn't feel at all restricted and didn't feel like I could swim in the pants. Truly a perfect fit for me.

Warm, breathable, and durable! 10/30/2018

I hiked over 20 miles at +/- 11000 ft over 3 days in these pants with temps ranging from 20s to 50s. Never got too sweaty and always stayed warm, and wore no additional layers other than underwear. We had about 6-8 inches of snow everywhere we went and I stayed dry the entire trip. Very durable against brush and extremely quiet. Best purchase I have made in a while!

Spot and Stalk Elk in Colorado. Temps in 20's in the morning and 50's during the day. Never had to change the pants and never had to worry about sweat. Pockets are amazing and placed perfectly. Couldn't have been happier with the pants.

Perfect fit for 34" waist with a little room for layering. Love the suspenders too.

Wish I could wear these everyday. 10/28/2018

These are amazing, I wish I could wear them everyday just around the house. I really like the suspenders, I don't care to hunt with a belt on when you're going from hiking to sitting all day long.

I love the pockets, zippered pockets are great but the cargo pockets are perfect! I can slip my mitts into them without having to look down, I can easily store a couple items I like to have quick access any anything I need to secure can be zippered away.


How it fits
With a pair of merino base layer the fit is pretty perfect, maybe a bit loose but I could fit some puffy pants underneath if needed.

These are my favorite hunting pants ever! 10/19/2018

I used these for a week long caribou hunt on the Alaska peninsula where it was 45 degrees and constant mist. These were water resistant enough to keep me warm and comfortable the entire time. I put the SEAK pants on when it rained hard, but the mist was not a problem in these pants. They are also light enough that I could hike in a few miles and never even think about being too hot or weighed down. Last week I wore them on a NoDak waterfowl trip. The sloughs were froze over every morning with temps in the upper 20's. These pants were all I wore and they kept me warm enough and dry enough the entire time. Great pants and if I had to pick one pair to bring on any trip, these would be the ones! Only problem is that they are out of stock!!!! Otherwise I would have all of the color options!


How it fits
I am a 33x30 in most pants and the M fit me perfect. They are a "slimmer" fit than more FL pants, but stretchy enough to be comfortable.

Put to the test 10/17/2018

These pants performed very well in damp conditions. Temps staying in the low 40s for the majority of a 3 day whitetail hunt. I’m cold by nature and didn’t wear a base layer under these since I had forgotten mine. They kept me warm and comfortable. Very surprised with the way the blocked the wind on the boat ride to the stand. Highly recommend.

2018 High Country Mule Deer hunt 10/13/2018

First use: Pants performed well during a backcountry elk hunt. Extremely quiet and comfortable. A little warm for the early season if you put on the miles. A little tight in the ankle area but manageable. Second use: high country mule deer. Same results weather was around 35 in the am and high of 50 mid-day. No issues. Got back to camp and found that the butt was ripped wide open. Didn't hold hold up in the dead fall. Padding in the knee and buttocks area would make this my go to pant. Fabric is not very durable.

Tight in the ankle area could be slightly looser

Exactly what I was looking for 10/12/2018

Simply amazing product. I used this hunting blacktail deer in Central California where the weather ranged from 65-80 degrees. Spot and stalk can get warm but this layer was very breathable and kept me comfortable the entire time. I also had the opportunity to hunt in Michigan for opening day of bow season where the weather went from 75 and sunny to 45 and rainy in a 24hr period. I stayed warm and dry during my week long hunt which is all i could ask for.


How it fits
I ordered XL which were perfect for length but the waist would never fit. Only way to wear these is with the suspenders.

Great pants 10/5/2018

Wore these during a fall Colorado archery hunt at 12K feet. Overall, great pants that kept me warm for the season. I did not wear a baselayer. The suspenders are great and can really be useful since my pants were big.


How it fits
Pay attention to the sizing. I wear medium for everything but really could have gotten a small in these. The suspenders help makeup for the loose fit.

Quiet and comfortable 9/26/2018

Pants are very comfortable. Have just enough stretch in them without feeling loose. Like the multiple slash pockets on the legs, each side has a zipper pocket and a pocket covered by a flap. Haven't gotten these out in the field yet, but they feel like an all-around weather pant - would be worried about getting too hot rather than too cold. Recommendations would be to have a slot for knee pads and a small boot zipper.


How it fits
Originally ordered in XL but they felt a bit tight in the waist and thigh, was worried how they might feel with a layer underneath. Exchanged for XXL and the fit is perfect.

Excellent pant 9/19/2018

These pants perform extremely well. The lining wicks away the sweat to reduce that clammy feeling after a hard walk. Super quiet and comfortable. I usually don't purchase lined pants but these are an exception to my rule. Great mid to late season pant.


How it fits
These pants are a slimmer fit than the corrugated guide pant. If your 5'8-5'10 and weigh in the 200+ Id recommend the large size pant.

Excellent Pant 9/10/2018

They aren't lying a single bit about the functionality of the pant in terms of the material used. I just took mine out for a scouting trip that involved a lot of hiking. Temperature sat around 58-59 degrees with a decently strong breeze. They kept me warm when I sat and glassed, I was a bit too toasty while hiking but the pants wicked away any moisture I generated and prevented me from getting cold once I sat down again. These pants are also extremely quiet and allow for a wide range of motion! I highly recommend these pants!


How it fits
Waist was a little tight (My waist is a 34) and the length was a little long. Doesn't take away from the overall comfortability, just means I need to lose some weight!

Great Pants, Very Quiet 8/30/2018

Just like the Catalyst Jacket, I was able to get these pants out during a recent cold front. The temperature was 45 when I left the truck. These things were the perfect weight for that temperature. Also, it was drizzling a bit and they performed well. Very quiet, very comfortable, well thought out features (pockets, suspender loops, etc.). We're back in the 80's now; but, I can't wait to get these back in the field once it cools off again.

Hey, nice pants. 8/30/2018

These are high quality softshell bottoms, though they don't stand out quite as much as the jacket does. They are durable, super lightweight, flexible, very quiet, and have awesome DWR. The pockets are a pretty cool design, and the included suspenders work well.

I have two gripes, however, but they're pretty personal. First, they fit a little tighter than the jacket of the same size, so depending on the weather you may have an issue with balancing your top and bottom base/mid layers. This leads into my second gripe, which is the lack of any leg zips. First Lite is trying to save weight, which I understand, and they probably figure you have to take your boots off anyways in order to shed mid layers so why bother. However, with the pants on the more fitted side I've found it more difficult that I would like to get the Catalyst pants on without them tugging up my base and mid layers. I think a knee-high zip would more than alleviate this issue.

If I had my druthers, I would make the pants a hair bigger, give them knee-high zips, and perhaps add durable waterproof nylon knee panels for making camp and crawling.


How it fits
On a proportionally-sized person, the large Catalyst pants leave less room for layering underneath than the large Catalyst jacket does. I wear size 36 jeans and the large fits well by themselves, but with an Aerowool base layer and a Furnace mid layer, for example, they are a tight fit.

Quality and comfort meet function. 8/29/2018

These pants are awesome. Almost like a beefed up guide pant. Very comfortable and not very loud so you can get away with treestand and spot & stalk.
Large size fit well with the Allegheny underneath. I wear a 36/32 pant. Waist and length were spot on.
Can't speak to durability as they are new, but they seem solid enough in the few hours I've spent in them. Dwr does its job and it's not hateful with the wind, but if it's overly windy I throw my rain gear on to stop it. It'll get you by in normal to slightly windy conditions. Overall I think these are a home run.

Skeptical of warmth, missing some features 8/29/2018

These are very well made pants, but I am skeptical of their warmth for stationary whitetail hunting activities such as hunting from a treestand. The material is much thinner than expected, and the fleece lined interior is only lightly lined - only slightly heavier than the obsidian pants. I expect I will have to add a puffy layer or additional baselayers when weather gets below 50F if I want to wear these pants. While I knew they didn't come with leg zippers, I find myself missing them from a previous set of softshell pants I owned. Also inner-thigh zippers are nice to have during high exertion acitivities. I can only hope these breath exceptionally well. Lastly the taper in the leg will make it all but impossible to put the leg over bulky rubber or insulated boots.


How it fits
These run very true to size and have an athletic cut. I am a 40W in plainclothes and while I can wear them with a single pair of underwear, any additional layering and they are too tight. The length however is perfect for me.

You need these pants! 8/29/2018

Short version: get these pants! Just the right insulation for an early season hunt and feel like they will be great in the mid to late season over a base layer.
Long version: Took these out on an Elk scout in the Canadian Rocky Mountains last week getting ready for opening day of Bow Season. First impressions they fit really well and are very comfortable for all day hiking. I’m 5’11” 190lbs (a bit stocky). Hiked two ridges and kept moving all day without sweating (weather was about 10 degrees Celsius) had a bit of light rain and lots of dew covered brush. Water wicked right off. Stayed warm and dry without a base layer underneath (got a bit warm when really pushing to the summit, but that’s to be expected with the warm-ish temp). The fit would definitely cover a skin tight base layer without any restriction. If you run a looser fitting base layer, and you have a stocky build, you might want to go up a size but it wouldn’t be critical. I wore these pants with the Kiln hoody and nothing under the hoody. These two items were enough to feel perfectly warm and dry all day while moving and I put the Catalyst soft shell jacket on while glassing on a ridge that had some pretty good wind in our face.


How it fits
I’m 5’11 and 190 a bit stocky and the large fits great. Could easily fit a snug fitting base layer underneath with a little room to spare so any moisture can evaporate. A looser fitting base layer might feel a little bulky under these pants.

A welcom addition 8/29/2018

Finally a softshell pant that is quiet and maneuverable! These pants are great. They are nowhere near as heavy duty as the north branch, but that is not really a bad thing. These pants are far more versatile.

very nice pants 8/29/2018

This is a great feeling pair of pants. The material is very soft and quiet. I am not a huge fan of the zippered pockets but its certainly not a deal breaker for me. The legs are more of an athletic fit and are somewhat tapered. I like the look when wearing these. They should fit nicely in tall hunting boots.

I wear a 36-38 pants and the large is right on the border. If you normally wear this size consider going up to the xl in this pant.

Exceeded Expectations 8/29/2018

I was very skeptical to wear any kind of soft shell material as a whitetail hunter from MS, but I was tired of the bulky/heavy options that provide the wind relief I need so I decided to tried these pants out. The few times in my life I have tried soft shell material out, the smallest movements were amplified for all wildlife to hear. After getting the Catalyst pants in, I was blown away by their lack of noise and friction while moving and sitting. I can’t wait to get these bad boys in the woods and put them to the test! Keep up the great work guys!

Good mid/late season or stand sitting 8/29/2018

These will be great for mid/late season or even early season stand sits. I'll be using them this weekend to sit in the mornings on the stand and they will be great for late season blacktail as well. Comfortable, stretchy, quiet.

Awesome pants! 8/29/2018

Great pair of pants! Super comfortable! They stretch and move with you so well, dont hinder or get in the way at all! Seem like they will do a goodjob breaking the wind and a perfect peice for late October into November rut. I've worn them around the house and practiced with them on using my climber and shooting in them as well as the jacket and I cant say enough about how great these feel and fit and are extremely "whitetail quiet".

These pants are quiet, durable and can great all season long. They are super comfortable for all day sits in the stand and can stand up to the elements on stalks in the thick greenbriars of WV.

Catalyst pants size large 8/28/2018

I puchased these pants as soon as they came out. I have been wearing them under various conditions in Maine for a few months now. My major concern was would they be as quiet as advertised - they are! For a soft shell to be this quiet walking through brush and moving I was very surprised. I also am impressed with the durability of the fabric. I have crawled on the ground, walked through thorns, and walked through dense forest without a single blemish. The temperature range varies with these because you can always layer, so with a good base layer I would say you would be comfortable in the lower 20s Farenheight. And without a base layer range would be 30-60. They are a warm pant so don’t expect to use them when it’s hot out.

Exactly What I Wanted 8/28/2018

I’m an Eastern whitetail hunter and I’m going on my first western hunt this October in Colorado. I literally shopped for months to find the right gear that would be durable, warm, and flexible enough to spend hours hunting/hiking in the back country. I looked at all the other competitors (Kuiu, Sitka) but the features and price point on the First Lite Catalyst pants set them apart. They have all the features I want without breaking the bank. Can’t wait to chase elk wearing these bad boys!

Very great product 8/28/2018

I used this to scout for archery opener last month. The entire weekend was 90 degrees. It held up pretty well up until 11 pm then I started to get warm. They held up pretty well for walking around all day along with they don't make a lot of noise. They can be used for both spot and stalk or sitting in a tree stand. I' really excited to use them for this season.

Confidence 8/20/2018

This pant is an absolute home run! Perfect for the “spot and stalk” hunt or treestand. Pants are extremely comfortable and non-restrictive “yoga proof.” The fleece lining provides excellent warmth and works well with the outer soft shell to block wind effectively. This system truly provides the utmost confidence and allows you to focus on your hunt and not on clothing failure. This is my new go to for whitetail hunting.

Awesome 8/18/2018

Just got back from a 2 week early August archery Caribou hunt in Northern Alaska. These pants were my primary set, paired with gaiters for tromping through the soggy tundra. While a more waterproof pant may have kept me a little drier, these were ultimately comfortable and dried out very quickly. Very durable and kept the stink down over the two weeks without a wash. They were warm, yet breathable. They've earned a place in my primary lineup for just about every hunt. Awesome pants!

Best.Pants.Ever. 8/12/2018

So I have a favorite pair of pants that I have owned for about 8 years. They were one of those multi-purpose pairs that you could wear to go fishing, for a hike, or to a decent restaurant when paired up with a polo or button-down.

I put these new Catalyst pants on, checked them out in the mirror a bit, did some squats to test the fit and stretch, and then I walked over to my closet to find my favorite pants, picked them up, walked to my kitchen sink, and then stuffed them down the garbage disposal. You may think i'm joking, but if pictures were allowed on reviews (get on it Kenton) I'd prove you doubters wrong.

These are by far, the best pants I have ever owned. They fit like a dream, are next to silent, beyond comfortable and I have full confidence in their technical abilities. I half-expected one day to find them draped around my vacuum cleaner handle, or draped in the kitchen sink, haphazardly doing dishes, as a set of limbless pants only can.

The first weekend that I had them, I went on a 6 mile hike here in Montana, in a temperature range of mid-upper 70's, and not ONCE did I actually notice perspiration forming on my legs. It was the type of weather where if i'd been wearing jeans, or thicker khakis I would've felt clammy about 10 minutes in, and it would have only gotten worse over time. It's odd, but I truly felt like my legs were right on the brink of getting sweaty/clammy, but that sensation never truly developed. Even if it had, I wouldn't have been disappointed, as these are 2 layer softshell pants with a fleece inner layer, but I was truly stunned at their breathability. The only test remaining is how they'll feel in colder weather, but I'm confident they'll be just as impressive in the Fall, and into Winter with the right layers of course.

If anything, I feel like these pants represent, or are indicative of where First Lite is as a company now. Earlier products and iterations were nice, and just as good as any other technical hunting wear, but with this current/new generation of pieces, they've surpassed what other companies are doing and there are no "oh but if only it fit better" or "if only it were quieter" comments that can be made. These pants fit very well, seem bombproof, are fantastic for moving around, keep you comfortable and look good while doing it. As the door gunner from 'Full Metal Jacket' said - "Get some! Yeah yeah yeah!"


How it fits
I love how trim/tailored these pants fit me. I hate when pants are too baggy as that's a. excess material/weight and b. higher potential of rubbing/swishing/sound and most importantly c. not stylish (got to look good in the hunting woods).

These pants fit me great, I wouldn't change anything. I'm roughly a 31" waist and the pants are snug but not uncomfortable at all. I'm 5'9 with normal inseam (about 31") and the length is perfect, they hit the middle-bottom of my boots and don't pull up when I kneel.

The most comfortable pant I might have ever put on...and I own the corrugate guide pants. The 37.5 fleece lining is super warm and the outer layer is absolutely silent. Just like the jacket, the Catalyst pants are going to be my go to pant for whitetail from mid September through December. If my wife wouldn't judge me, I would wear the catalyst system every day from fall until spring.

Truly silent, but very thin 7/29/2018

The Catalyst Softshell Pants are truly silent outerwear pants. I got them in Cipher and the pattern works great for breaking up my outline in the trees. My only concern is the material holding up for more than one season. The brush and briars poke right through the thin material and I see a bunch of snags turning into tears.


How it fits
The pants are the right length for me, but pretty snug along the legs. I don't think I will be able to wear my polar weight base layer during the late deer season.

Quite and comfortable 7/22/2018

My first pair of first lite pants ,didn’t know what to expect on how it would feel sound and actually work out on the field . When I went out for some white tail and the temperature here in Canada was around 11 degrees Celsius , with a little precipitation, the pants made my hunt comfortable and worrie free about if my legs would get cold or damp. These pants are recommended buy in my opinion, first lite really brought it to the table for everything that a hunter could ask for .

I wanna give these pants a 5 star review but the pants legs feel like im wearing skinny jeans. but I believe this is due to my athletic build but I think this my not be a problem down the road when I'm not doing stationary stand hunting. I will right another review come winter to let you guys know how these pants performed during winter in Georgia. The pants feel really well made an they feel really warm so far. But due to the tight fit in the leg area I'm gonna find it hard to layer up for winter. But then again from what I've so far from how warm these pants are I may not even need layering

Great all around softshell pant! 7/9/2018

I haven't been able to put these pants through the "ringer" yet but wanted to give a review on the construction and fit of the pant. I've owned other manufacturers soft shell pants and these are by far the quietest I have had on. Definitely quieter than the North Branch pants were. The construction looks and feels great with quality zippers and well sewn seams. The DWR coating is the real deal as well- I ran the pants under a faucet for 1 minute and no signs of wetness inside the pant. They aren't rain gear but they will definitely get you through an unexpected shower. As far as the warmth of the pant I would give them a comfort range of 32-55 degrees for me. Obviously, layering as it gets colder would be needed but the fleece lining has a good weight to make it a usable pant through a variety of climates.


How it fits
I wear a 34/36' waist (depending on the brand) and have a 32' inseam. These pants in a large are just about perfect for me. I was always between a M and L in First Lite pants and with the new sizing the larges are definitely the right choice for me. Plenty of room for layering and not too big with a belt or suspenders while wearing alone. The length is a touch long, but with no zippers on the bottom this doesn't bother me.
