Duckworth's fitted Men's Vapor Brief is the world's best wool underwear. Nothing keeps you more comfortable where it counts than all-natural, Montana-grown Merino Wool spun and knit into our proprietary Vapor Wool fabric. Our Vapor Wool is naturally antimicrobial (odor-free), itch-free, cooling, breathable, quick-drying, moisture-wicking, and oh-so soft. Just imagine the comfort, even in the most hot and humid conditions. This American-made Merino Wool underwear also boasts a brushed waistline and functional fly. What more can you ask of a pair of briefs? American-made with Montana wool, these men's briefs are available in multiple colors.
