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

SO WHAT DOES AEROWOOL DO?

ELIMINATE SMELL

The unique molecular structure and neutral charge of wool fibers prevents 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.

INCREASE STAMINA

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.

MAINTAIN STEALTH

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.
