Obsidian Merino Pants

Silent, odor resistant, and comfortable from 100 degrees into late season, the Obsidian merino pant takes the torch from the best-selling Kanab 2.0 pant with the fit being based off our hugely popular Corrugate Guide Pant. The Obsidian’s ergonomic design and proprietary, stretch merino/nylon fabric work in conjunction to move and flex with the body and provide maximum durability  all while preserving the qualities you love about Merino. Reinforced with rip-stop nylon, this woven merino pant has no UV signature or shine and fends off odor-causing bacteria better than any synthetic.  Stretch nylon panels also enhance range of motion and provide durability and support in high stress areas. The Obsidian pant is equipped with detachable suspenders for a superior fit with pack or harness and can be used with other First Lite pants. This piece is machine washable and will dry quickly over a branch or on a line. These features make the Obsidian a superior choice for a wide range of stationary and active hunting applications.

    Can't wait to hunt with theseReview by Bull_Fighter
    The fit is nice. Never owned a pair of merino pants and I can't wait to put these to the test this September! They feel great and have plenty of room to move around in. The cipher pattern is great too. (Posted on 8/14/2017)
    Not up to the taskReview by Tom
    I am a grad student wildlife researcher and hunter. Let me say that I love everything first lite- the merino wool shirts, socks, and boxer briefs! So I bought these pants to use for my field research and hunting in california's dreaded A zone. I wore these pants twice and they were not able to withstand chamise, thorn bushes, mixed chaparral, etc. they have already ripped. Also, the front pockets are huge and low, filling up with debris faster than anybody's business. It's clear these pants were made for road hunters or trail walking; they cannot withstand backcountry off-trail beatings. Hopefully the first lite crew can strengthen the design for the next pants they create, but I'll need to be convinced if I am to ever purchase a pair again in the future. (Posted on 8/13/2017)
    RoomyReview by SteveinAK
    I am between the medium and large sizes. I ordered the larges and they are just about right in the waist (I am a 33/34 waist in jeans), and I like the option to use the suspenders instead of a belt. I like the cut of them. I have thick legs and rear and many hunting pants get tight in the thighs. There is plenty of room throughout those areas and in a full squat or lunge there is no "hang up" spots where the fabric gets tight. I like the way the buttons for rolling up the pants are hung from a ribbon as opposed to sewn directly on the pant. If you hate the button, you can cut it off without damaging the pants, and then you won't kneel on it anymore.
    On a side note, I think that the new conifer color is right on, much more subtle than pine was. (Posted on 8/9/2017)
    These pants are awesome!Review by Shaun
    I bought a pair of these pants after the crotch in my Kanab 2.0 Merino Pants ripped. These pants are very well made and I love the pockets on these. Your first impression when you get these may be "they feel too soft and thin to wear out in the woods" but talking from experience they are excellent. I highly recommend these pants!

    Great pantsReview by Andrew
    These are great and handled a wide range of temps (40-80) very well. I never got swampy or cold. They're extremely quite through the brush and stretch and give everywhere I needed them to. I'm not a huge fan of the ribbon button at the knee. I don't like feeling things toss around on my legs and wish it was a button stud or attached directly to the pant. I like the built in ability to roll my pant legs just not the way the button was executed. If you're looking for an all around pant add these to your cart now. (Posted on 8/5/2017)
    Awesome Product!Review by Richard
    Got the Obsidians early summer and tried it out on a grizzly scouting trip. At 4,000 plus feet elevation in the mountains of Alaska, these pants kept me warm and comfortable through out the hole day even when the wind staterd blowing. Like the Kanabs, I am very impressed on the Obsidians. My new all season go to pants. (Posted on 8/2/2017)
    Exactly what I was looking forReview by Tyler
    Finally had a chance to put some time in these scouting and setting up cameras. It's been hot up here (Between 85-95) and these pants have performed great in the heat. They are super breathable and don't lock in the sweat. The fit is great, a little looser up top and tight around the boots. Definitely the most comfortable hunting pants I've worn in the heat, so they should be perfect for early season. The pockets are also well placed and not over kill. I'm looking forward to seeing how they hold up over time and how warm they'll keep me during late season hikes with the long underwear. All in all a must have piece of gear in my opinion.

    Great PantsReview by Alex Sterling
    I ordered these pants in large which is what I order every other bottom in at Firstlite and they fit great. They have a looser fit than the corrugates, so if you want a tighter fit, you may want to size down. I however like the looser fit. They are also durable. The thorn bushes I have been through don't phase them. They breath well and I consider them a piece of gear that you can wear year round with the right layering. They also look great. I wouldn't hesitate to wear the solid colors out in town to a restaurant or bar. (Posted on 8/1/2017)
    Must ownReview by Trevman
    I finally got to wear my obsidians scouting the most grueling country side this past weekend! As you know, in the end of July it gets really toasty here in Idaho. I had so much mobility and they kept me dry as I sweat the whole day! These are a must buy for the backpack hunter! (Posted on 7/31/2017)
    Sent them back the day i got themReview by OWL
    To get this straight, I have never left a review in my life. I felt as if I owed it to anyone who would read this and make a decision before spending $200 on pants. I bought these pants with the intention of using them to scout, hunt, hang stands, etc. After opening them (they are a lot darker then they look in this pic) I was immediately surprised at how soft and thin these pants are. They also felt almost too soft to wear into the woods, kind of like a pair of pajamas. When my wife came home and asked if those were the pants I paid $200 for she laughed at me. I just do not see the value in these pants. Keep in my mind this is my personal opinion and I have no expertise in clothing but I have been a hunter my whole life and these just are not what they seem to advertised online.

    waiting to testReview by Great pant
    Just received these a week or so ago, I like the fit as I am a small and most waist to length ratios don't work as I have a longer inseam then most smalls. The pockets are awesome. They fit and feel great, Alaska Dall sheep will be the test! (Posted on 7/14/2017)
    Great early season/active hunt pantsReview by joshkolasch
    A true to fit hunting pant, the obsidians blew me away with how quiet and comfortable they were, extremely breathable to keep you cool during warm days, and warm enough to keep you comfortable when the temperature starts dropping. Great pants for active hunting and for early tree stand use! (Posted on 7/6/2017)
    Great pant - nice update on the Kanab 2Review by NODAK
    Finally arrived. Great pant, well built, cut perfectly for me, and comfortable to boot. I'm 5'7 and 155lbs, SM fit great.

    These will be my go to pant for early season. (Posted on 7/6/2017)
    Very HappyReview by Gage
    I was finally able to get these pants out and give them a try in 90+ degree weather. I must say they are going to be good in the early seasons. I was able to keep cool and still keep my lags shaded from the sun. I especially liked the new pocket placement, my pants were able to stay a little looser when sitting down when my thigh pocket was full. I also think I will enjoy the button on the leg so I can roll my pats up when I want to cross a small stream. (Posted on 6/30/2017)
    Great for the ladies too!!Review by Jeannie
    I needed a quiet pair of merino pants and figured I'd try the men's Obsidian Pants. VERY impressed, they are quiet, worked well in the 40-80 degree weather I was hiking in and fit great. I'm 5'7'' and typically wear a women's medium, I bought these in a small and they are perfect. Love the suspenders as well! Two thumbs up First Lite (Posted on 6/27/2017)
    Great QualityReview by Randall
    I really like these pants! The way they fit as well as the pocket layout. The suspenders rock, especially while wearing a pack. They do run true to size, I order XL when I normally wear a 36 comfortably and with the stretch they allow the XL were a little large on me; returning for L. (Posted on 6/23/2017)
    Great Pant!Review by Jesse from AK
    Just received these pants in the mail so haven't got a chance to test them in the field yet but they seem like the perfect all around hunting pants for here in Alaska. The fit is pretty spot on, I am 5'9, 150#, 30" inseam, and the small fits perfect. Depending on the company I wear a medium and sometimes a small in pretty much everything. I followed First Lite's sizing guide to make my decision on these pants. The elastic in the waist band makes them variable for those people that can be between sizes on some products. First Lite nailed it on these pants! (Posted on 6/20/2017)
    GREAT PANTS!!Review by Michael
    Great all around weather pants that are tough and fit great, The articulation is great so it stretches when you go up and over logs or bend over. Really glad first lite kept the button on them so you can fold up your pants for river crossings or when its hot. (Posted on 6/19/2017)
    Big BrotherReview by HuntORE
    6'4, 195 lbs, Large tall. The 'tall' works for me. These are very quiet pant, especially compared to the Corrugates. I was expecting them to be a bit heavier weight, they are not heavy at all, but they feel durable. I'm confident they will keep me warm when i need to be. Rolling up the legs to create some "morts" (man shorts) is a nice touch. A do it all pant for sure. (Posted on 6/15/2017)
    Not what the Kanab 2.0 used to beReview by Jeff
    I blew out the crotch in my Kanab 2.0's and RMA'd them. It took almost two months, but I was sent a new pair of Obsidians as their replacement, which was nice. Unfortunately, these pants are not what the Kanabs used to be. They are cut more like the Corrugates, which I own, wear constantly, and love, but the wool version doesn't seem to handle that cut as well. The pants are bunchy in weird places like the thighs, knees, and crotch. Also, I really liked the pocket configuration of the Kanab's, but that's personal preference. I miss my Kanabs. If you like your Kanabs and something less-than-catastrophic happens to them, take them to a tailor to have them repaired. Otherwise they'll be swapped for a lesser pant. (Posted on 6/9/2017)
    Wow!Review by Rich
    These just arrived in the mail today. A buddy had the original Kanabs, and I was hesitant to order because I did not like the fit and felt like pockets were insufficient. The new Obsidians are awesome. Same great feel, but better fit and a great pocket setup. Cant wait to get these out in the field soon. Large was spot on, I am 6' and 200 lbs. (Posted on 6/8/2017)
    Better than Kanab 2Review by Idahizzle
    Just got my Obsidians and I can see why they're better than the Kanabs--I like the cut better as they just seem quieter and less likely to snag. Great pockets and the size was spot on in a large. (Posted on 6/7/2017)
