Cut for a cool, casual look, don’t relegate the boxer short to home. With a pull-on waistband and on-seam side pockets, it balances functionality and comfort. Cut from our signature Japanese Admiral Crepe with a subtly textured stripe, this distinct style has an elegant drape for a polished take on shorts.
We are committed to positively impacting the people who wear our clothes, our industry, and our planet, beginning with our fabrics. Our signature crepe is woven with triacetate, a fabric made from acetic acid and wood pulp sourced from certified responsibly managed forests.
