Stretchy and slim-fit merino-blend briefs made with icebreaker's corespun fabric, the Merino 150 Anatomica Briefs offer the support and comfort you need in a classic underwear design. The ultralight 150gm fabric is made with merino fibres wrapped around a nylon core, for underwear that is soft next to your skin. The slim fit includes a supportive, contoured pouch and the flatlock seams prevent chafing. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre that naturally resists odours, keeps you cool when it's hot and warm when it's not, and lets your skin breathe for comfort all day, every day.
