The Step One Men's Boxer Brief Fly in Dark Grey is anti-chafe bamboo underwear with a front fly opening for easy access and a six-inch inseam, designed for men with thicker legs. It has the same construction as the standard Boxer Brief. 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. The fly makes it a practical choice for the office or formal wear. Sizing is fitted, so if you are between sizes, size up. Machine washable.
