Pure wool underwear is recommended for the health and comfort of men and women, particularly those engaged in hiking, professional driving, skiing, cycling, climbing, camping, horseriding, all outdoor adventures, and long periods of sitting. Isn't that almost everyone? Wool is more breathable than cotton, and stays fresh naturally. Today's pure and superfine merino wool is machine washable, non-itch and lightweight. Briefs for women, boxers for men, and long john leggings for all.
