This shirt's tightly-woven nylon fabric blocks 98% of harmful UVA and UVB rays for a UPF of 50+--the highest attainable--without messy sunscreen lotions or chemical treatments. The open-knit construction allows for total breathability, helping keep the body dry and cool by wicking away moisture and providing an air-conditioned effect on hot days. The fabric can also be worn in the pool or surf, yet dries in minutes once out of the water. The collared shirt offers classic styling with a six-button front, a generous cut for wearing over a bathing suit, and a split bottom for comfort. Two front pockets. White. Provides a generous, roomy fit. Specify women's sizes XS (4-6), S (6-8), M (10-12), L (14-16), or XL (18). (1 lb.)
