The new SUNWT Shirt collection builds on a generation of trusted SUNWT performance and style. These shirts are right at home on the casting deck, surfing sets or just hanging out. SUNWT Shirts are constructed from tightly woven, lightweight microfiber polyester with quick dry technology. This fabric offers a bit of stretch and feels like silk next to skin. It protects you with 35 UPF sun protection every minute you wear it. Our SUNWT Shirts are also effective base layers when conditions get cool. Add a SUNWT Shirt to your sun protection system.
