The Step One Men's Trunk in Ahoy Sailor is anti-chafe bamboo underwear with a four-inch inseam, a sleeker cut designed for men with thinner legs. A hidden elastic 3D Comfort Pouch surrounds and supports everything, keeping it in place all day. UltraGlyde ride-up resistant panels on the inner thigh reduce friction and stop the legs riding up, whatever you are doing. The fabric is 95% viscose from bamboo and 5% spandex, giving a super soft feel with the right balance of stretch and support. Bamboo viscose wicks away moisture to keep you fresh and dry, is breathable and hypoallergenic, and is produced in a closed-loop system. Choose the Trunk if you have thinner legs; the Boxer Brief has a longer six-inch leg for thicker legs. Sizing is fitted, so if you are between sizes, size up. Machine washable.
