Unlike previous generations of sun-blocking garments that were heavy and hot, these lightweight cover-ups are comfortable yet effectively block up to 95% of the sun's harmful UVA and UVB rays. 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. Ideal for all outdoor activities, the fabric earned a U.S. patent due to its complex open knit design and treatment with UV inhibitors, a combination that effectively reflects, refracts, and absorbs the sun's harmful rays, and which provides a simple alternative to messy sunscreen lotions. Because the fabric is equally effective wet or dry, the cover-ups can be worn in the water, yet dries in minutes once out of the pool or surf. Polyester fabric is colorfast, even in salt water or chlorinated water. Machine wash. Made in the U.S.A. Long-sleeve, crew-neck pullover. Please specify White or Khaki. Women's sizes S (8-10), M (12-14), L (16-18), XL (20-22) and Men's sizes M (40-42), L (44-46), XL (48). (1 lb.).
