Nipple chafe sucks.. if you know, you know. NipEAZE protects your nips while running, working, surfing or body boarding. They are super thin, transparent and hardly noticeable, even under the skimpiest material (good for Hollywood Premieres as well as races!) They are waterproof and secure enough to be worn by triathletes and surfers, but come off easily and pain free in the shower. So good!
