Super Armadillo Nano is a top-of-the-line gaiter with a thermoregulation and self-cleaning feature embedded in the upper section. The material adjusts to your temperature - keeps you warm or cools you off as needed and no water or dirt gets absorbed by the material. The upper section is paired with a lower section which is abrasion and slash / puncture resistant. Both sections are waterproof and breathable to keep you dry from the outside in and inside out. No snow, slush, rain, mud, scree, rocks, debris and dust are able to get into your boots or socks with these on and they also save your lower legs from brushy conditions. This is the choice for mountaineering, backpacking and hunting.
