Obsidian Merino Pants

Ripstop Merino and Stretch Nylon

$180.00 USD

Color/PatternFirst Lite Cipher
Add to Wishlist

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.

Great Pants

I just got back from a Colorado late season elk hunt and these pants held up great. I wore them as a second layer and I stayed warm while sitting and glassing. These have also become my favorite pants to wear around town during the winter. Definitely worth the purchase.

Product Size: M
Location: Tree stand
Primary Use: Whitetail Bowhunting
Quiet and comfortable

These pants are the first first lite item I bought. I love them! They are comfortable, light weight, and quiet. They fit great, not too baggy but not too tight. Great early to mid season pants and you can layer underneath on colder days and stay warm.

Product Size: M
Height: 6'
Weight: 165
Fit Comments: Waist fit great, length was a bit short in the inseam
Location: Whitetail hunting in Wisconsin
Primary Use: Outer layer for early season, mid layer for late season
Excellent quality, a bit short in the inseam

Received these pants along with several other items that I purchased a few weeks ago. My first impression is that they are really well made, and the attention to detail is noteworthy. Needed to exchange them for a medium tall as the inseam seemed to be a bit short for me (6' tall, 165 pounds) and they felt a bit high water on me, especially when I sat down. Looking forward to getting the medium tall in the mail so I can put them through the wringer with my other FL gear. If they are anything like the rest of the First Lite pieces, I am confident they will perform with excellence!

Product Size: L
Height: 6 feet 2 inches
Weight: 195
Fit Comments: Large in thighs
Location: North Alabama
Primary Use: All types of hunting
Great for its purpose

These are great all around outdoor and hunting pants. They are very comfortable and give great range of motion.The pockets are perfect.
As far as temperature rating as a stand alone item, I would say they are about like a your typical Carhartt style pant for warmth. But they are also comfortable In warmer temperatures like a fishing style pant. I layer with a couple base layers underneath and they are good down to around 32 degrees in a tree stand. Anything below 32 and you’ll want more insulation. For active hunts these pants are definitely the go to in hot to cool temperatures.
As far as durability, they are not exactly brush busters. But for typical uses they are wholly adequate. I just wouldn’t go running through a briar patch.
I usually wear 33-34 or 34-34 pants so I got a large. I have skinny legs so the large is a little baggy In the thighs. The medium tall would probably be better for me, but the little extra room is great for layering underneath.
These are quickly becoming my favorite hunting clothing item, so I would highly recommend these for their intended uses. Just know the limitations.

Excellent Pants

I bought these for fall hunting and for coaching in the late fall (football) and spring (track and field) in Northern Minnesota. These pants are excellent. They are cool when they need to be and warm when they need to be. I would highly recommend these pants. I will be purchasing more in camo for fall bow hunting for whitetail in Northern MN. The weather can go from warm to cool and even cold and these pants are perfect. Fit is spot on for me. I am 5'8" and about 180 pounds (fit 180). Excellent pants!
