Tired of cold legs? Then try Woolpower Merino wool underpants. These 400 Series underpants are about twice the thickness of the 200 series. Use them for extreme cold. All Woolpower clothing is made from "non-itch" Merino Wool Terry Cloth and they will keep you warm in cold, even wet conditions. They have been field tested worldwide for over 10 years and we swear by them! This is the best wool undergarment line we have ever seen. The secret is a combination of Merino Wool and polyamide in a unique "terrycloth" knitting method which gives the products higher insulating values and better moisture control than other wool products.
For best results wear them next to the skin. They do not itch and are so shrink resistant that you can even machine wash them in warm or hot water, and dry them in your home dryer. (As long as they do not go over 140 degrees.)
Unlike poly-pro type garments, this wool stays odor free much longer and it is very fire resistant.
