Building on the success of our popular men’s jacket, the Brooks Down vest delivers ultralight, packable, backcountry insulation in an even lighter package. Built with 100 grams of DWR-treated, 800-fill power, 37.5-DownTek, this piece provides advanced, active insulation that fights off moisture to keep you warm, dry, and comfortable.
When you are miles deep into the backcountry, counting ounces is vital but never at the expense of staying warm and protected from the elements. With that balance in mind, the Brooks was designed using 50% more down than its closest competitor to be the lightest weight possible while ensuring best-in-class warmth. Whether you are packing into tahr country in June or looking to take the chill off those March stag hunts, the men's Brooks Down Vest is the trusted choice to guarantee your warmth while keeping your gear lightweight.
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, both Fusion and Cipher dissolve into their surroundings unlike anything else.
First Lite Fusion and Cipher are the most versatile patterns available to hunters because both are carefully designed to ensure concealment no matter the proximity, season, or terrain. Created using the same scientific platform and developed by Joseph Skinner, both Fusion and Cipher use proprietary pattern technology which provides equally exceptional concealment at close range and a distance--whether in the trees or on the ground.
First Lite's new 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.
Fusion has become the most trusted pattern in breakup camouflage. From dry eastern lichen covered rock and tussock land, pine, and to the West Coast bush, 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.
Both First Lite Fusion and Cipher incorporate large regions of light and dark colors to distort and hide the shape of the hunter's body by creating a visual which works against the signature human figure.
After closing the distance, texture-based disruption is integral to hiding a hunter’s shape and location. A scattering of small to medium-sized elements using the pattern's color palette blend the hunter into his surroundings to ensure prey have a more difficult time visually identifying a threat.
The large and small disruption supports the overall disruptive coloration found in First Lite patterns, which use a set of colors fine-tuned to blend in with the surroundings while contrasting against body outline.
First Lite Fusion and Cipher use color and nature-based algorithms to confuse the prey's focal vision. The pattern's proprietary design creates a built-in sense of depth which fools the prey's depth perception. Finally, the controlled contrast and disruptive coloration of First Lite Fusion and Cipher distort prey's peripheral vision.
First Lite patterns incorporate proprietary crackleture which further contrasts against a hunter's body signature. This innovative feature provides the next level of versatility and effectiveness not matched by any other pattern.
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.
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.
