COTTON STRETCH: Spun in pure, premium cotton yarn with a hint of Spandex fibers, Calvin Klein’s signature men’s underwear wicks away moisture to keep you cool and dry. SUPPORT + COMFORT: Featuring a contoured pouch for a supportive fit, Calvin Klein’s mens briefs have a soft, flexible logo waistband that stays put without too much compression and retains its shape, wear after wear. SIGNATURE FIT: Designed with full back coverage and a low-rise waist that sits below the hip. DESIGNED IN THE USA: Calvin Klein underwear for men is created by its NYC-based global design team using premium imported materials. CARE: Machine wash cold, tumble dry low heat. We recommend hang drying your briefs to extend the life of your garment.
