Polypropylene Underwear

OuterSports has been selling 100% Polypropylene Underwear and accessories since 2000. We buy in bulk so we can get the product for less and pass those savings on to you. 100% Polypropylene Underwear does not absorb water. Instead, it spreads sweat and moisture evenly across the fabric so that it will dry quickly and keep your skin dry. It really is an amazing material. You can throw a set of polypro thermals in the washer, pull it out after the spin cycle, hang it up to dry, and it will be dry within minutes! This makes polypropylene thermals the perfect product for ski or snowboard trips. You can hand wash it in your hotel and hang it up to dry and it will be ready to go within minutes. Our thicker fleece polypropylene is the warmest thermal underwear we carry. Polypropylene retains more heat than any other fabric making it the warmest thermal underware you can buy.
