JWP Men's 30% Merino and 70% polypropylene underpants. The underpants feature a man’s fly, flat seams that do not hurt, and are antibacterial. The underpants are made of a functional rib knit and feature a finely combed blend of Merino wool and polypropylene. The polypropylene provides for the best possible moisture wicking away from the body surface towards the outer layers of clothing.
