WHAT IS AEROWOOL®?
When temperatures reach for the ceiling but the hunting is heating up too, you need every advantage you can get. Aerowool is the perfect marriage of First Lite's super-fine merino wool and the 37.5 Technology® utilized in our Outerwear System in a 65% / 35% ratio. The result is an ultralight base layer that fights stink and noise like the merino you love but dries three to five times faster and brings improved durability to the table thanks to the 37.5-infused fibers. Whether you're hiking through high desert pursuing a heavy pronghorn or scouting for that giant whitetail buck in the back forty, Aerowool is your best hot weather, active base layer.
What Does Aerowool Do?
The unique molecular structure and neutral charge of wool fibers prevent the attraction of odor-causing bacteria. Enhanced by hydrophilic 37.5 fibers, moisture is quickly pulled away from the skin and transported through the fabric, eliminating the moisture needed for bacteria to form.
When your body is not spending its resources and calories on cooling or warming its core, you're more efficient, you have more stamina, you think more clearly and you can make a better shot.
Delay the Onset of Sweat
Aerowool works in the vapor stage before you break into a sweat. If your activity level increases suddenly or the temperature heats up and sweat appears, First Lite's Aerowool dries three to five times faster than competitive merino products.
Leaning on merino wool's inherently soft fiber, Aerowool is one of the quietest base layer systems in the marketplace with its virtually silent movement.
ACTIVE PARTICLES DO THE WORK
With 37.5 technology, active particles are permanently embedded at the fiber level to capture and release moisture vapor. Not only do these particles provide 800% more surface area, but they also provide a unique driving force to remove moisture vapor, unlike any other technology. By responding to body heat, these particles use energy from the body to accelerate the conversion of liquid to vapor, which significantly increases the dry times of the fabric. The hotter the user gets, the stronger the driving force of removing moisture becomes, and the more comfortable the garment stays.
Having seen all of the benefits and performance in the field of 37.5 in our outerwear, we applied the active particles to a synthetic fiber and then wove it into our industry-leading merino wool. By blending the two fibers, we married the benefits of merino wool with the performance of a synthetic fiber.

Merino-X brings increased warmth, improved structure and resistance to tears and bagging to merino wool. Merino-X is built with a ultrafine merino wool in a high loft, interlock knit to create styles that surpass expectations in the broadest range of temperature and weather conditions. Blending a small component of spandex into this knit, these lofted interlock pieces can withstand extended hunts in the field, regardless of the season.
