Ara Swim Tights XS - Black Driftwood. The technical excellence of the prAna Ara Swim tight is complemented by feminine styling. Flattering contrast stitching adds durability and flexibility, while a gusset provides a complete range of motion. 1mm hyperstretch neoprene is overlaid, inside and out, with recycled poly and spandex for comfort. A neoprene skin at the interior waist helps its retro high rise maintain a secure fit.
