The Outdoorsman is our latest cold weather face covering that features our newest protective details. The nose bridge web flips up to create a seal that prevents cold air from being pulled in as well as exhalation and condensation from fogging up your glasses. This new feature also creates an extra layer of seal in conjunction with the copper wire nose form. The body of the mask is constructed of traditional Hounds Tooth pattern 100% wool material that is a classic outdoor pattern used by Hunters and Outdoor enthusiasts dating back to the turn of the century. This classic wool fabric was used for Jackets and Shirts as well as Caps to help retain a layer of warmth around our bodies and we felt that it was time for a new function as a cold weather face covering. The inside layer is fused with 100% Poly Interlining and it offers structure to the mask as well as a second layer of filtration. One more feature is our Folded Loop label which serves two functions, first it wicks and retains skin oils away from the body fabric and it also has a place to personalize it to avoid possible mixing or loss. Adjustable straps help insure a secure and snug fit. We have a limited supply of this fabric so get them while you can. Stay safe and warm out there!
