Coldpruf 100% Polypropylene Long Underwear Pants for Women

Polypropylene thermal underwear gives you the most warmth for your money. Polypro retains more heat than any other fabric, yet it is very lightweight. It also dries extremely fast so it keeps your skin warm and dry. The US Navy and US Coast guard are required to wear polypropylene whenever they enter cold water because of polypro's ability to trap and retain heat next to your skin helping to prevent hypothermia. Coldpruf utilizes extra fine polypropylene yard to make these polypro thermals as soft as cotton. With proper care, these will last year after year. They are great for touring cold weather regions like the Arctic and Antarctica as well as Alaska. If you are planning to go on a cruise to one of these regions, the cruise company typically recommends that you wear polypropylene. 1
