Obsidian Merino Pants

Ripstop Merino and Stretch Nylon

$180.00 USD

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.

Don't Wash these pants!

Perfect Western Pant

I wore these pants on a 14 day moose hunt in 2019. I brought two pair of these and two pair of a competitors pants that I know are proven to test durability and comfort for a long hunt. These Merino pants in my opinion are far superior to softshell pants. They breath much better when you are crawling up mountains and busting through muskeg and tussocks. The weather during this hunt ranged from 10 degrees and snowing to 60 degrees and sunshine. These pants were worn for 5 days each, with depending on weather merino boxers or full length long johns underneath, I never felt like I was over or under dressed. These pants are also thin enough that they can easily be layered under rain gear or a pair of puffy pants for glassing. The only downside of these compared to their shoftshell counter part is it doesn't quite protect from the moisture as well but will dry just as quickly. I highly recommend these pants for any type of hunting where movement is the strategy of choice.

Poor Quality

Especially considering the price of these pants, you'd expect them to be much better quality. I'm just not entirely sure how you're supposed to hunt in these. They're way too thin to be used in places like my home state of Arkansas where you can expect to encounter quite a bit of brush. That's fine though, they aren't supposed to be brush busters. Just, seriously, do not even look at a thorn - they'll rip.

So you can't really use them to stalk or spot and stalk or otherwise really hunt. Oh and they're great when wet, right? No, not really. Wool is supposed to insulate when wet, but wearing a synthetic base layer and these pants during a light rain I couldn't stop shivering. It was in the 50's, but my $180 pants forced me to head back due to weather. They're so thin you can only really depend on them to keep you warm in situations where a comparable synthetic pant would also keep you warm. Except a synthetic pant will shed water or not get shockingly heavy with water. Also, these take forever to dry. I've hunted in Pendleton wool shirts for years without the same issues these pants present.

Then you can hunt in these when you don't leave a trail and it's dry out, right? Nope! I got holes in the crotch of these pants after a single 10 mile day. One real day and I had significant holes in the crotch from where my thighs rubbed together. Also the zippers broke immediately.

I've had the stupid pants for three seasons now. They are tattered, have holes, broken zippers, get heavy and cold when wet, and cost me $180. Who the hell are these for? Stand hunters. But then you could basically wear camo pajama bottoms and be just as warm for significantly less cost.

changed product style with no warning

I have a pair of these pants purchased in the summer of 2019 - they are among my favorite pants of all time. I purchased two more pairs this winter. Unfortunately the style has changed. The waist is now smaller, the length is longer, the lower leg is more voluminous, and they have eliminated the shock cord closure at the cuff. It's troubling that these changes occurred without warning. More troubling to me is that customer service wouldn't comment at all on the change. Perhaps they aren't aware of it, or it was an unintentional change. I suppose this is what happens when your product is produced on the other side of the world. I attempted to return these pants that aren't the same pants I know and love. Unfortunately for me, I removed the tags (understandable in my mind given the excellent fit I expected from such a high priced product). I was informed that they are now completely nonreturnable. The customer service representative went as far as suggesting I should just try to sell them through an online classified market. No comment on the fit change. Unfortunate stance and the lack of product support is telling. My advice to buyers would be to try on every item you order as the fit seems pretty variable and quality control is low. I personally intend to direct my purchases towards a company that stands behind their product.

Obsidian and kiln

I recently switched to First Lite gear for my hunting applications. I was skeptical because the price I’ve always been kinda cheap when it comes to camo and gear. I’ll just say I’m glad I made the leap to First Lite. I will be a lifelong customer here. The merino definitely is a game changer. I got a 250 kiln hoody and the obsidian pants. I’ve noticed that the Fusion pattern definitely breaks your profile up and that the wool helps keep scents to a minimum. I guided all season in them and the talus touch gloves. I liked them all so much that I got my wife the kiln and the Alturas pants for her spring bear hunt. Can’t say enough good about my obsidian and kiln hoody. I’m a brush buster and was worried that I’d tear up the obsidian pants but for as thin as they are they are durable as hell!!!! I use my gear hard and they have stood up to a whole season with only one tear in my kiln hoody which for as hard as I hunt I expected a lot more this year than just one tear. I love the versatility of them as well. Warm weather they breathe and cold weather they keep you warm. I’ll be getting more gear from this company for sure. First Lite has my business for life.
