Crank or plank in this sassy but serious tank top. Its highly technical polyester/spandex fabric blend is super soft and fast drying. The lightweight-mesh shelf bra is supportive and allows for optional use of soft cup inserts. A surprise detail: Three skinny straps stretch across the deep, open racerback, staying put in long reaches and showing off your strong serratus posterior. This hip-length tank provides maximum comfort under a harness and doesnt fall in inversions. Fabric is bluesign approved.
