AquaSport SPF15 3.5 fl. oz. Liquid AquaSport SPF15 by All Terrain. AquaSport SPF15 Description: If your idea of fun involves lots of water (kayaking, surfing, triathlons, windsurfing or just hangin' at the beach, etc.), then we designed waterproof and sweatproof AquaSport Sunscreen for you. Its unique super dry formula ensures a non-slip grip on your surfboard, paddle, fishing rod, ski rope, or whatever equipment you rely on in the water. And our formula won't run into your eyes, but if you do get it in your eye, it won't sting. Sun and water are hard on skin, so we added antioxidants and moisturizers to AquaSport to promote healthy skin. AquaSport is available in 3.5-oz tubes of SPF 15 and SPF 30+.
