SlipIns SurfSkin Minis are made with a combination of Nylon, Polyester, and Spandex. This material is silky soft and feels great against your skin yet is durable. People who wear them say they're softer than a baby's behind and feel awesome. This short tight fitting upper bodysuit provides excellent sun protection with 60+ SPF and preventing rash development. It can be worn under a wetsuit or by itself. It is similar to, yet more eye catching than, a high rise spring suit. On those sunny, warm water days, your SurfSkin Mini is perfect for a stylish session in the water, whether surfing, paddle boarding, kayaking or generally enjoying your water sport of choice. SurfSkins Minis can be worn with or without a bathing suit.
