At Extreme Outfitters, we’ll be the first to say that snug-fitting undergarments are the key to staying warm when out hiking, biking, hunting, or working in the cold. That’s why we carry men’s performance shirts, tactical field leggings, and snug boxer briefs from top brands like Tasc, XGO Tactical, Under Armour, and more.
