Merino Wool
Why Merino Wool Works
Sheep have evolved over hundreds of thousands of years while living in Siberia’s freezing high alpine slopes and the blistering heat of the Australian Outback. Their wool coats both shelter them from the cold and protect them from the heat. Merino wool base layers do the same against our skin--they regulate body heat and keep you comfortable in a broader range of temperatures. When it’s hot, wool transports moisture and warm air away from the skin and disperses it into the air. When it is cold, it traps the warm air from your body and keeps it close to the skin.
No Smell
“They can hear you twice, see you once, but if they smell you, they’re gone.” Every hunter knows the importance of minimizing human odor and there’s no fabric better at keeping B.O. to a minimum than wool. Wool absorbs 30% of its weight in moisture which then passes through the material and evaporates instead of remaining on the skin.
No Shine
Wool absorbs UV radiation through the entire UV spectrum, unlike some synthetics and other naturally occurring fibers. This means merino doesn't shine from light reflection, which helps hunters evade detection when crossing slopes, gaining ridgelines, and maneuvering through country.
No Sound
Wool is inherently quiet. Wool doesn't flap in the wind, doesn't shear when you walk, or crackle when it's cold. All of First Lite wool products are made with high-quality, low micron fibers and yarns made out of long filaments, which helps reduce any remaining noise.

Our Wool
Sustainably sourced, ultrafine merino wool built for uncompromising comfort in the harshest conditions.
Wool Quality
World's Finest Wool
Merino is not a grade of wool, it's a specific breed of sheep that produces nature's most advanced performance fiber. Where traditional wool measures upward of 25–40 microns in diameter, Merino fibers fall between 11.5 and 22 microns. For scale, a single human hair measures around 40 microns. That microscopic difference is what makes merino wool so soft and wearable in additional to all it's great properties: it breathes when you're working, insulates when you stop, and stays warm even when wet. First Lite builds on nothing less.
Sustainable Sourcing
RWS Certified
All of our wool suppliers are RWS certified. The Responsible Wool Standard (RWS) is a voluntary standard that requires all sites, from wool farms to the seller in the final business-to-business transaction, to be certified. RWS farmers and ranchers are evaluated against animal welfare, land management, and social requirements set in the standard.
