Derek Rose Ethan Men\'s Hipster. Our Ethan quality combines a subtle marl with the stretchy softness of a blend of micro modal and elastane for underwear that feels and looks fantastic. Our hipster is a classic of jersey underwear. It\'s basically a fitted boxer — or a brief with legs, if you will. Cut from a blend of 91% micro modal and 9% elastane, our hipster provides exceptional softness as well as excellent fit. This softness extends to the fabric-covered waistband for maximum comfort. The closed front and manual welt hems give this hipster a minimalist look.
