The Xtremen Sensual Boxer Brief is sleek and sporty, with a touch of sexy, thanks to the semi-sheer horizontal stripes. These athletic boxer briefs are made from a super stretchy microfiber fabric that forms a sleek fit that nicely defines all your masculine contours while offering long-lasting comfort and support. The long length of the legs protects against rubbing and chafing, making them ideal to layer under workout wear.
