Once you try our Merino Wool base layers you’ll never go back to your old style synthetic underwear. Merino Extrafine wool is the ultimate in luxury and softness. This superfine, non-itchy, wool is smooth as silk, at the same time offering unsurpassed versatility over synthetic or cotton fibers. Merino wool wicks moisture away from your skin leaving it dry and warm, not wet or clammy. It’s breathable, releasing excess heat when necessary and locking in warmth when it gets cold. Wool is also flexible, easily moving with you but always retaining its original shape, even after years of use. Better yet is the fact that it’s machine washable and odor resistant. Our light-weight line will keep you cool when it’s warm and warm when it’s cool. Perfect for the hunter that will be in and out of the elements. You’ve got to try it to believe it, but you won’t be disappointed. Mid-weight, Black.
