Talk about an ingenious inVENTion! Revolutionary Breezeshooter® Briefs Underwear amps up breathability to a whole new level of cool "air-go-nomic" comfort. Every inch of this ingenious fabric is packed with microscopic vents for maxed-out airflow – so breezes really do shoot right through! Better yet, the 89% polyester/11% spandex fabric has built-in stretch for total freedom of movement. Soft and substantial elastic at waistband and leg openings keeps undies where they belong, so no bunching, shifting or twisting. Wicking and antimicrobial finish nicks sweat and odor so you can breeze through summer heat!
