The best boxers for any hunt
The best boxers, are those you forget you are wearing. These Red Desert Boxers fit great and don't ride up or fall down. They hold everything in place (without being restrictive), and keep it all nice and dry. I never knew how much I needed these until I actually used them. I can't recommend these highly enough.
- Cory on 10/2/2017
Comfortable and practical
After 2 days of wear during active elk hunting at 8000- 10200ft were still comfortable and held no noticeable odor.
- RFelkGuide721 on 9/25/2017
Best underwear ever, wear them for everything. Medium fits me perfectly, 6'0 tall 190lb slim build
- Lucas on 9/13/2017
Smooth Fabric
Very comfortable and well made. Only issue I had was that it seemed like there was some extra fabric around the waist and upper leg that made for a loose fit.
- Kevin on 8/30/2017
Awesome first lite never fails
Again I can't say enough about first lites gear. I absolutely love these boxers. I've only tried them on one time but I can tell they are absolutely perfect. Can't wait to use them when the season starts in a week!!!
- Johnny on 8/18/2017
Great pair for early or late season
These boxers are a great fit. Not too long and not too short. They are thin enough to wear in hot weather and not feel overheated.
They are a tad bit on the itchy side when you first wear them, but they soften up after a few washings.
I would recommend these if you want some longer boxers than the benmore
- Kelly on 8/12/2017
Best pair of skivvies out there
Both the Red Desert boxers and Dobson Aerowool boxers are the best underwear I have owned. I can run a trail marathon or spend 4 days wearing them in the backcountry with no chaffing or smelling my junk when I sit down. I like them so much I have purchased 6 pairs and wear them everyday, yes I have them on as I am typing this. The First Lite boxer briefs have replaced every pair of performance boxer briefs I own.
- Esquire_Outdoors on 8/9/2017
Held up to week in NWT for dall hunt. Only boxers I wore, no stench afterwards. Perfect for ultralite hunting.
- JustinTX on 8/3/2017
Way better than aerowool
These are amazing. The length keeps them from riding up, they are snug and hold everything in place yet don't stink after a long hike. I tried the aerowool version but for me, they did not have the same comfort level.
- Mk7mmSTW on 7/31/2017
No stank.
I hunted elk in the San Juan mountains near Ouray, CO for 8 days with two friends. After over 27 miles and 28,000 feet in elevation covered I wore two pairs throughout the whole week. Sweat, work, and elevation are no match for these things. I heard they wouldn't smell bad so of course I smelled them and they had no stank even after 4 days of hard hunting during a warm season.
- Matthew on 5/1/2017
Perfect for Pants and Parts
These are my go-to undies for any sort of strenuous outdoor pursuit. They keep my twig and berries supported without feeling constrained, they don't stink after a few days of wear, and they keep everything dry and feeling fresh. Oh, and they're insanely comfortable. Easily the most comfortable underwear I own, to include ex officio, UA, and Smartwool. The only reason I gave these bad boys 4 stars is because I like to wear shorts in the summer time (Sky's Out, Thighs Out) and the longer legs on these peek out of the bottom of my shorts and get really exposed when I sit down. But if I'm wearing long pants and I'm outside, you can bet that I'm wearing these.
- Matt on 4/18/2017
Cold nuts ruin ruts
These boxers are awesome for 3rd or 4th season deer hunts! I normally don't like boxers this long but the extra length is great when the temps are low and prevents them from creeping up and causing chaffing. They are a little too warm for my liking for early and mid season but that's what the Aerowool stuff is for. I love the comfort and flexibility of these. You won't regret the purchase if you hunt in the cold. No holes or pilling after 2 years of frequent use!
- JayCreegs on 4/13/2017
Never recommended underwear before this
Just buy it is all I have to say. Weekend hunting trips with no showers and get home and they still don't stink. Plus they are really comfortable.
- Brad B. on 1/2/2017
Great comfort but lacks durability
I have three pairs of these boxers. Let me say they are amazingly comfortable and awesome for hunting and backpacking. Ill go days wearing them and no smell and my body is clean. Temperature regulation is awesome as well. With all that being said they do not last long. For how much they cost I would expect more than 6 months out of them. I do wear them regularly but I have boxer briefs I've worn for years and no sign of failure. I have a real tree for 6 months and it is basically shredded in the perineum area (taint). The black ones for 3 months and they are starting to do the same. The third pair is real tree as well but isn't showing signs of failure yet. So that's $150 in underwear with only one pair still strong. Disappointed with durability for the price. Will give smart wool a shot and see if they hold up any better. Great product but for me not worth the $50 price tag.
- Robby Dougs on 12/19/2016
Best $50 You Will Ever Spend!
Some of you may be questioning your sanity when considering spending $50 for underwear, but I promise once you experience the level of comfort and performance these provide, you will be back with your wallet open! My initial purchase was only 2 pair to give them a try and have enough for weekend adventures, but now I am back to buy a few more to grow my collection. I truly believe there is nothing more comfortable and find myself never wanting to take them off even when lounging at home alone! Ridiculous comfort!
- Hammer79 on 11/21/2016
A Critical Part of Your Layering System
I had a hunting buddy this season who invested in good pants and outerwear but didn't upgrade his cotton boxers, only to complain about being sweaty and uncomfortable. In order for your breathable outerwear and other layers to perform as designed, you also have to wear an underwear base layer that manages moisture properly. After a weeklong hunt this year, the Red Desert Merino Boxers didn't stink. They are comfortable and they dry fast. These are the last pair of undies I'll need for hunting or any active outdoor activity.
- RyanM on 11/15/2016
Must have!
These boxers , are the perfect addition to your hunting clothes. The perfect layer to keep you warm . When there isn't a need for a full !ength base layer!
- George on 10/27/2016
The best so far
These Red Desert Boxers have replaced my synthetic Exo boxer briefs. I purchased these earlier this summer and they have been on a rafting trip and two backpack hunts so far. The fiber is super soft. The length helps to keep things from getting bunched up in crotch area, and when it does after some long hiking and climbing, the length helps you pull things back into place without having to make things awkward for your hunting pals as you pick a front wedgie.
Truth be told, the first pair I ordered ripped at the seam after my second trip. I contacted FL about the issue and sent them a picture of the seam failure. They contacted me back and I filled out the warranty info. A week and a half later, I have a new set of boxers. Customer Service was easy to work with and the new set will be put to the test this winter on some longer hikes and snowshoe trips.
- Steve S on 10/25/2016
Red Desert 170g Merino Boxer Short
Great product a must have for any situation. The extra lenght makes a big difference.
- John on 9/2/2016
These Red Desert Boxers are flawless! Once you wear these next to skin, you'll never want to wear another material again. I have worn these for days without a wash working out, at work, and hunting; casually scent checking them each day to learn how long I could actually go without a wash, and I was shocked!

The merino aids with scent and pulls moisture away from the body to elevate chafing. I can take two pairs of boxers into the back country, and while stand hunting here in Michigan, and switch each day knowing they will be comfortable, scent free, and reliable. The best boxer I have tested hands down!
- Nick K. on 8/12/2016
The Perfect Underwear.
Like the new Dobson aerowool undies, these are friggin' amazing. I prefer the Red Desert's in colder weather. They perform greatest during late hunts or early spring shed hunting expeditions. I can't seem to own enough pairs!
- Caleb on 8/6/2016
Never turn back
I did not have a good first impression with the first pair I bought. This was my fault as I ordered the large when I should have ordered the medium. In my defense, I thought the medium's waistband would be too tight judging from the sizing charts.

The large was too loose everywere except the waist band. The bottoms of the shorts hung over my knees (to the center of the kneecaps) And the seam that runs down the crack of the butt really tucked away between the cheeks. This made for a very uncomfortable first impression.

I decided to order the medium size and give them a chance before I gave up. Talk about a game changer. They fit perfect. No more baggy boxers. They stay right where they need to be on my lower thighs. No longer have a crack riding seam. And the waist band isn't too tight. Very warm when they need to be and not too warm when they don't need to be. Never had that sweaty wet spot that you get when you start working hard. Very comfortable next to skin. No chafing. And I am a huge fan of them being tagless as well.

The only thing I that I have an issue with is when I go to squat and bend over, the waist band does pull down a little. Not enough to have a plumbers crack, but enough that I feel the need to reach back and pull them up a little.

I can honestly say that I have never worn a more comfortable pair of underwear.
- Cody on 7/7/2016
Best athletic boxer I've ever had
I own 2 pairs of these and love them. They are comfortable , supportive and breathe well. I have worn one pair for a week with a quick wash or two in a creek and no problems. I've worn them in 90 degree Arizona days hunting and In the snow at 10k. Mine are about 2 years old and are holding up just fine, not had such luck with other merino boxer brands.
- james on 6/14/2016
Better than anything else
All other brands (underarmor, dry wear, ice breaker) I have tried stretch out, bunch, chafe and/or give me a wedgie. The red deserts however do not. They have stayed comfortable regardless of the kilometres and elevation I have put on them including packing an elk out 6km.

The one problem I do have is my legs are rather large and the bottom of them still stretch out a little bit past their elastic point. I am a 34-36 waist and have both large and XL and both have the same issue. It doesn't really affect the performance but does affect the comfort slightly... Not enough to bring it down to 4 stars though.
- Jeffrey on 4/19/2016
Got me through Ranger School
I recently graduated ranger school and I have to say that one of my
biggest keys to success were the red desert boxer short. They did more
than pay for themselves when I wore the same pair for ten days at a time
in the rain, crawling in the mud, and very long walks with a lot of
weight on my back. They kept me warm when it was snowing in the mountains
and while crawling through chest deep water through the swamps. They
never lost their elasticity and sagged or bunched in the crotch no matter
how wet or how many consecutive days they were worn. In the end I never
chaffed once despite all of the physical events and endless walking. I
will be wearing the same pair this summer bow hunting hogs and this
fall/winter as various game seasons open. Thank you for having the same
level of commitment to creating all your products to a standard the
competition can stand up to. RLTW!
- Mason on 4/15/2016
best boxers ever
wear for days and cant smell myself when I climb in the sleeping bag lol
- lucian on 4/11/2016
must own
why in the world you would choose to cradle your bits and pieces in crappy cotton or some synthetic fabric that rides up your inseam and doesn't let things breath ? whether its hot or cold these are the best boxers you can get !
- David on 4/9/2016
I don't hunt without it
I wear them on every hunt. You never think you'll pay this much for boxers, until you try them then you are HOOKED. I have wore them for days on end, and they DO NOT STINK!!!. Merino is hands down the best, and in my opinion the cut and fit if these boxers are wonderful.
- N. Hedrick on 4/9/2016
Buy a size smaller
The wool is comfortable and light but I would recommend ordering a size smaller than what you traditionally wear.
- Sean on 4/8/2016
Great but...
Love the boxers. The only thing I would suggest is moving the extra logo on the center back of the waistbelt. The extra fabric rubs with a heavy loaded pack. Keep the primo gear rolling!
- Harlan on 4/7/2016
Exceptional performance in harsh Alaskan conditions
I have used these underware for two years now on multiple hunts here in the bush of Alaska. they have performed flawlessly during all temperature and weather conditions. Even after dumping a raft on a remote float hunt they wicked away the moisture and dried out extremely fast. My go to base layer without a doubt. Buy them.
- Scott on 4/4/2016
Its like having your junk cupped by the hands of angels.
- Spearo on 8/31/2015
I definitely hesitated at purchasing boxers for this much money. But they are worth every penny and then some. They are absolute incredible at pulling moisture away from your body and keeping you comfortable in all temperatures.
- BNC Bucks on 8/19/2015
I wear these every day. Best boxers on the market. NEVER ride up, and keep the odor to a minimum, even after multiple days on the beat.
- John on 8/7/2015
I really thought I would never buy $60 boxers, but I got a pair, and let me tell you now all other boxer briefs are ruined for me, I now have only firstlite boxers...
- TheRichOutdoors on 4/10/2015
I just got back from a 7 day ski trip in Colorado and wore one pair of red desert boxers while skiing. I wore Patagonia Capline boxers after skiing, but the red desert took all the punishment! They still smell like new and merino continues to amaze me. They are crazy comfortable and I really like the longer length. I also wore llano and chama base layers and they performed great as well. Can I convince first lite to make a 3/4 length long underwear?! I don't like my long underwear interfering much with my socks and most first lite socks are pretty high anyways. Who can I talk to about this??
- Nat on 3/6/2015
Best $60 I've ever spent
A$$ sweat is a thing of the past! These things are amazing, I put on my first pair and and ended up wearing them for week straight. Only stopped then because two fresh pairs arrived in the mail, and they still don't smell funky! Never would have believed how good they are until I tried them.
- Nathan on 2/3/2015
Best underwear on the planet
Wicks moisture away better than any other garment and fits great.
- rusty on 12/31/2014
I want 10 pairs in my underwear drawer.
- Jarrod on 10/22/2014
$50 for underwear?! Yes, please!
Let's be real, $50 is a good chunk of change to shell out for some underwear. The idea borders on ridiculous. That is, until you actually try them. First Lite merino is top notch, so the comfort next to skin is a given. What surprised me was that they do not ride up the leg whatsoever, so chaffing of the inner thighs will never be an issue with these. Also, the waistband is equally as comfy. Also, no matter how swampy it gets "down there," these just won't stink. Awesome product...
- Jefe on 10/7/2014
You know when its time
With cotton or synthetics you know its time when things just need to be changed. The First Lite Red Desert Boxer shorts do not fall into that category. All the comfort you need, thermal regulation and wait, do you smell that? Nope not with these...
- IATrent on 6/30/2014
Better than Compression Shorts!!!!
Today was my first outing in these boxers and definitely not the last. Being an athlete I have always worn compression shorts while playing sports or in the woods. I was looking for a boxer that was comfortable like my boxer briefs but protected my thighs from chaffing while hiking. Not only do these boxers do that, they also don't ride up at all. If I had the money I would get rid of all my boxer briefs and switch to the Red Desert Boxer Shorts.
- Bears86 on 6/24/2014
Best Field Boxer Ever!
These are amazing! Worth every penny; sitting in a duck blind or in the these and so do the jewels.
- Squatch on 6/24/2014
The red desert boxer shorts greatly exceeds my expectations. Well worth the price! Used them recently during a scouting trip in the Arizona high country and after 2 full days of hiking around some rugged country in 75+ degree temps, they didn't hold that normal funk that regular boxers do. The length is a little longer then most, however, the didn't ride up nor did the restrict any movement. Highly recommend to anyone looking for a high quality piece of under garments
- scott on 6/18/2014
Cotton feels even worse after wearing merino!
These boxer shorts are without a doubt the best I've ever worn. So comfortable I almost thought I forgot to put them on at times. The length was perfect under my pants/long shorts. Never bunched up/rode up when pulling up my pants/shorts. NO chaffing! Probably one of the best things was not being sweaty down there after hiking... dry and comfortable all day. I purposely wore them to work for 5 days to test out the smell/feel of them... completely impressed to find that I could have worn them longer but just the thought of it changed my mind... :) Great buy to anyone considering them. I will buy more!
- Almost like going commando! on 6/18/2014
Nice and Comfy
This is a well made product that fits true to size, and is always comfortable no matter what the conditions outside or in. I do recommend this product.
- bsm on 6/18/2014
Favorite piece of clothing
I never thought my favorite article of clothing would be something that couldn't even be seen but these Red Desert boxers are so awesome I'd have to list them at the top. They are comfortable, warm and scent free. I bought 2 pair that I wore on a 13 day BC wilderness horseback hunting trip and they were everything as advertised. They also kept me from getting chafed through long days in the saddle. I wear them every time I deer hunt and they fit the bill here in Georgia as well. Job well done to the Sitka folks.........
- John on 6/18/2014
Everyday wear
These boxers are extremely comfortable, I wear them everyday.
- AZMike on 6/18/2014
These boxers are no joke. Incredibly comfortable! They will keep you happy where it matters most. I bought one pair last season and this season I purchased several more for everyday use. If you're skeptical, don't be. These will not disappoint.
- BromadTheForager on 6/1/2014
Awesome undies
I was so impressed with these as a piece of hunting apparel that I purchased another 5 pair for all the other days of the week. These are great from the coldest days in Idaho to the humid tropics of Southern China.
- Mike_A on 5/29/2014
Perfect Product
FirstLite crew, Thanks for making a superior product! I wear the Red Desert under my ski pants in the winter and under shorts in the summer for all day comfort, warmth and breathability. When I wear draws, the Red Desert is for me!
- Torres on 5/29/2014
Only Boxers You'll ever Need
Any type of climate, these boxers are the perfect starting point to your layering system. So comfortable I wear everyday. The longer cut and overall comfort will keep me using the Red Desert for a very long time.
- Rodgesa on 5/29/2014
wear everyday
First Lite boxers shorts are the most comfortable pair of underwear I have ever worn.
These are great for hunting but also good for everyday wear. Great temperature control.
Highly recommended them.
- bigbuckhunter33 on 5/27/2014
Always comfortable!
These are the basis for the best layering system. You can wear these for days on end, always staying cool and comfortable in warmer conditions, then helping your boys to stay warm in sub 0 temps! I never leave home without them when heading to the back country!
- Mtbowhunter on 5/27/2014
Best Place for Your Junk
the combo of the Thermal boxers and the high socks have changed the way I layer in certain conditions where I will go from working up a sweat to standing still. when I am hiking I slide the socks down allowing a large portion of my leg to stay cooler longer.
