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 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!

Excellent, well tested product

As a bowhunter, the need for quiet clothing is not negotiable. These First Lite pants have been well tested all over the West from Arizona to Alaska and have quietly passed with flying colors. Hands down my favorite pants to date. If you are truly serious about getting off the grid and putting in the miles on a Western hunt, I will recommend no other pants.

Versatile durable functional pant

If you are a fan of hunting with merino wool, these pants are for you. I wear these pants either early fall whitetail/bear or for spring turkey. This pants are first rate--quiet as a mouse, durable, functional, and extremely durable. First Lite's merino fabric does a fantastic job of insulating while breathing. The stretch fabric makes these pants very functional. I love that the pants come standard with the suspenders. Perfect athletic fit. I would definitely recommend.

Dang. These are great.

I must say, these were the first real commitment I've made to hunting clothing. I got by with other stuff, cheaper stuff, noisier stuff. But with the fluctuating temps in early season hunts in southeastern Wyoming, I decided to roll the dice. These have become a daily-wear item for me. I wear them as often as I can without causing suspicion from my wife or coworkers. With a simple base layer underneath, these pants have allowed me to remain comfortable at a huge range of temps, have gotten me through thick timber, dense sage brush, and ranges of pretty warm temps to sitting in a snow storm. I'm fairly amazed. The pocket setup seems intuitive for me, and while others may be used to it, the suspenders were game changing for me. I lack a certain volume in the glutes, and with a belt and pack on, my pants were constantly getting pushed down. Now, with the suspenders, I don't even think about it. Throw my pack on, sling my rifle, and get to hiking. I absolutely love the Obsidian pant. By next season, I'll pick up another pair and keep them in near constant rotation. They are the pants I wear for hunts, and they're the pants I throw on when I'm lounging. I never thought I would write those words, but for a not necessarily cheap pair of pants, they're worth every dime for me.
