First Lite Obsidian Foundry Pant


Hunting early season stags or summer chamois hunting, you can rest assured First Lite has your pants covered. The new Obsidian Foundry pant continues to incorporate field-tested and approved ripstop merino into the outerwear's main body to better regulate temperature, remain silent when moving, and resist the build-up of odor-creating bacteria. Key friction zones through the Seat, Crotch Gusset, and Lower Leg have been constructed with durable stretch nylon to provide snag and tear resistance where it is needed most and offer moisture protection through DWR treatment. To top it them off, the Obsidian Foundry pants feature and include a new suspender system with reduced hardware and friction points for hunters who pack out heavy.

First Lite Camo


First Lite patterns obliterate the human shape by utilizing a proprietary mix of nature-based algorithms in coordination with disruption and focal confusion techniques. Put more simply, the relationship between colors and shapes has been specially designed to fool the brain by resembling recurring patterns found in nature. Derived from the golden ratio found throughout the natural world, Specter™, Typha™, Fusion™, and Cipher™ dissolve into their surroundings, unlike anything else.
First Lite Specter, Typha, Fusion, and Cipher are the most versatile patterns available to hunters due to their careful design and ensured concealment no matter the proximity, season, or terrain. Created using the same scientific platform, all four of First Lite's proprietary camo patterns use trademarked technology, which provides equally exceptional concealment at close range and a distance. When it comes to whitetail hunting, First Lite Specter uses the proven technology of its predecessors (Fusion and Cipher) but expresses shapes, colors, and fragmentation unique to the whitetail environment and tree canopy. Similarly, First Lite Typha expresses environmental abstracts consistent with marsh and field environments fit for the waterfowl hunter.

First Lite Comouflage Technology

First Lite Fusion

Fusion has become the most trusted pattern in breakup camouflage. From western lichen, sage, and pine to eastern deciduous hardwoods, the Fusion pattern and color palette are engineered to excel in a vast array of landscapes. Hunters virtually disappear into their surroundings at any distance – short or long – lending confidence and near-perfect stealth, whether in the trees or on an alpine ridge.


First Lite Cipher


First Lite's Cipher pattern leverages the proven working principals of Fusion and applies them to landscape palettes with less color. Cipher emphasizes the narrower color spectrum found during the autumn and winter months in both hardwood and western environments. With its muted coloration and Fusion-inspired DNA, Cipher is a deadly weapon in every hunter's arsenal.

First Lite 37.5™ Technology

More Breathability Means You Stay Drier than the Competition

When First Lite engineered their Outerwear Collection, they looked closely at every fabric technology in existence. Having the pick of the litter, from better-known outerwear technologies to more niche, lesser marketed performance fabrics. The truth in outerwear manufacturing is that the brand in question can generally use whichever fabric they choose. The costs vary as does the performance, but if a brand is willing to pay for the best, they can choose to incorporate it into their offerings. First Lite chose 37.5 because third party empirical testing as well as extensive field use their our own employees left them greatly impressed by the superior performance of the fabric. The bottom line is that 37.5 breathes at a rate that is anywhere from 50% to 300% better than any of its competition, while offering waterproof levels that were within a 5% tolerance of our competition.

First Lite's DNA is active, extremely vigorous mountain hunting. Based in the Rocky Mountains and literally testing products year round in some of the steepest, most demanding terrain in North America. Breathability becomes paramount when you're climbing significantly steep, rugged slopes with heavy packs in less than ideal weather conditions. If you sweat under your outerwear and the fabric doesn't allow that moisture to escape, you might as well expose your base layers to the elements and skip the outerwear all together. 37.5 technology does the absolute best job of transporting that moisture from your base layers to the outside of the First Lite garment so that you can remain safe and dry while exerting yourself in the most brutal of weather conditions. This is why First Lite selected 37.5 Technology over other fabrics and has enjoyed award-winning products ever since.

The Science behind 37.5 Technology

Comfort in clothing is greatly influenced by the temperature and humidity next to skin known as the microclimate. For the average person, the body strives to maintain an ideal core body temperature of 37.5° C. You are most comfortable when the microclimate next to your skin has a relative humidity close to 37.5%. When you are in this ideal 37.5 comfort zone, you are also in your ideal performance zone. 37.5 technology helps your body manage the moisture in your microclimate to keep you in this “37.5 zone” of comfort and performance.

Your body already has the ultimate thermo-regulating system. The perspiration vapor that comes off of skin during activity cools the body when working hard. In fact, each gram of evaporated sweat releases 580 calories of stored heat. Unless this water vapor can be removed from the microclimate, it builds up in clothing, footwear, or gloves and creates a clammy and uncomfortable microclimate. 37.5 technology works to enhance the body’s natural cooling mechanism—the body puts out sweat to cool it down, 37.5 technology removes it from the microclimate.

With 37.5 technology, patented active particles permanently embedded at the fiber level capture and release moisture vapor. Not only do these active particles provide 800% more surface area to the fiber, they also provide a unique driving force to remove moisture vapor unlike any other technology. By actively responding to body heat, the active particles use this energy from the body to accelerate the vapor movement and speed up the conversion of liquid to vapor, significantly increasing drying rates. This means the hotter the user gets, the stronger the driving force removing moisture becomes—and the more comfortable the garment remains.

37.5 technology works to keep the optimum relative humidity in your microclimate so your body more efficiently maintains an ideal core temperature, enabling you to perform better, longer. Fabrics made with 37.5 technology dry up to five times faster than similar fabrics, diminishing wet cling. 37.5 technology is made with naturally derived materials so there are no harsh chemicals to irritate your skin. 37.5 active particles are permanently embedded into yarn and will never wash out or degrade.

Obsidian Pants Dry Earth

Was quite optimistic when I purchased these pants being Australia based rather than US and to wether they would “cut the mustard” to our harsh conditions. I purchased the dry earth version as again believe that this would best suit where I hunt. Cam sent them out pronto and they arrived within a few weeks. texture of the fabric is a little different to what im used to but put them on. I ordered a 34/32 and they were spot on with the sizing and fitted well with room and stretch where it needs to be. Fabric has movement to it which was great as the gully’s demand clothing to stretch when climbing up and down. Loved the cargo style pockets but would have been slightly better if positioned slightly more forward. The braces took a little to get used too but once you get used to them theres no going back to a belt. Loved the way that the leg slightly tapper’s in at the bottom so your not scraping against the other leg. performed very well going through the blackberry bushes with no rips or tears and certainly didn’t pick up any burr’s. They are little pricey and the temptation to not buy them is quite high but they are worth every cent of your hard earned $! . Overall a 9/10 from me to the point that ive messaged Cam for another pair!! If your looking for something that will last, made and fits well then look no further as these pants are awesome. Would just like to add that my dealings with Cam and the boys re their customer service has been the best ever so buy with confidence.

Obsidian Pant Review 1 Year On

Hey everyone, well its been just over a year since owning these pants and they have been outstanding and to be honest I don’t wear any other pant now whilst hunting. they look a little beaten up but are still going strong! I only have one issue and that they have shrunk in size in the leg by about two inches and an inch of the waist so considering in turning them into shorts😂 I purchased a second pair as was so impressed but have not yet worn them and whilst out last i noticed that either id grown or they were getting shorter. well put them up side by side the second pair i bought and yes they are heaps shorter. with that said these are the best hunting pants I’ve owned just slightly disappointed on the shrinkage.

Love these pants!

Have just completed a 4 day hike ranging from -5C to around 15C, and the pants performed exceptionally.

Plenty of stretch for climbing and squatting, and comfortable to wear all day - I didn't bother changing after the camp was se tup.

They breathe well and I didn't notice any heat buildup when really cranking up the mountains in the sun. At night when it was freezing I put on some merino thermals underneath and was plenty comfortable. The wind doesn't cut through these pants, even though they breathe well.

I liked the pocket setup - snacks and stuff were easy to get to without having to remove my pack, and the zippered sections were good for keys and things I didn't want to lose.

I'm a 32 waist, but had to return a pair of 32s because they were too loose on me. Cam responded very quickly and set me up with a pair of 30/30s which fit perfectly.

The braces were great, although I had to move them either forward or behind my pack straps. Other than that I forgot I was wearing them.

The bottoms of the legs folded well under gaiters with no chafing, and it was great having the DWR on the seat for just plonking down on wet logs or rocks.

These are my go-to bush pants now, for sure!
