Sweat less, exert less energy, and stay more comfortable with First Lite's Proprietary Aerowool Technology.

WHAT DOES AEROWOOL DO?

ELIMINATE SMELL

INCREASE STAMINA

DELAY THE ONSET OF SWEAT

MAINTAIN STEALTH

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.

BETTER TOGETHER


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.
