Obsidian Merino Pants

Ripstop Merino and Stretch Nylon


Color/PatternFirst Lite Cipher

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 garment, but terrible material.

Loved this garment for its fit, comfort and use in high heat. However, FL needs to enforce the seat area. Larger gusset of perhaps stretchy synthetic so as it doesn’t wear through as mine did in crotch/seat area. They are being returned as damaged in exchange for Corrugate Guides.

Great Gear!

Great pants all around! Got them for my Elk hunt in CO and can't wait to use them again. All around 5/5. Will definitely order more in the future!

Great Pants.

I really liked these pants. To be honest some of the reviews about the quality had me hesitant to try them. I am glad I decided to. They worked really well in the Colorado Rocky Mountain back country. I did not wear a layer underneath. They wicked away sweat, but still retained warmth. I had no issues with them ripping and it was fairly brushy. There are better products for serious brush busting, so I believe selecting the right product for the situation is important. I used these pants when making long hikes in extreme elevation and intermittent rain, cold, and heat... early season conditions. They kept me comfortable in all scenarios. I would not expect them to hold up to thick brush and thorns, but there are other pants specifically made for that.

A World of Yes

I used these for pre-season scouting in Texas in 100+ degree heat. Did great on keeping all the stuff off me while keeping me comfortable. I also used this for Elk hunting in Colorado and they did great on the cool mornings to the warm afternoons back to the cool evenings. I have seen some people say they are too thin, I did not experience that. They are thin, but very tough. No issues at all.

Must have pant

These pants are a must have for early and mid season hunts as an outerwear. Don't be fooled by the Marino, these pants are impressively durable. For 7 days I was busting through brush and pines and scrambling rocks bit looking at them now you wouldn't be able to tell. I wished I had my Corrugate pants for this purpose until I put these through the wringer. Truly odor resistant. I would wear these for 3-4 days at a time during high activity and warm temps with no smell. I highly recommend these pants. My only complaint is the fit. These wore a bit large on me. Utilizing suspenders helps and makes it less noticeable. If you have an athletic body type, they will fit a bit baggy.
