We married our top-shelf Merino Wool for odor mitigation with the incredible moisture wicking properties of our outerwear technology, 37.5 by Cocona, and created Aerowool--the ultimate active hunting and warm weather ultralight base layer. Anytime a premium is placed on moisture evacuation during active hunting or use in hot climates, First Lite's exclusive Aerowool is your new go-to base layer. This could be the most comfortable, versatile and important addition this season. The First Lite Neck Gaiter can be worn around your neck for warmth and comfort and then easily pulled up over the back of your head and up over your nose for extreme cold and maximum concealment. The Neck Gaiter is also a great piece of gear for winter fishing, snowmobiling, skiing or snowboarding when the weather gets cold and nasty.
