We are proud to usher in a new generation of 12WT performance and style. This shirt collection is constructed from lightweight microfiber polyester with quick dry technology. This fabric offers a bit of mechanical stretch and feels like silk next to skin. These shirts provide 35+ UPF sun protection every minute you wear them (wet or dry). Our SUNWT Shirts are also effective base layers when conditions get cool. Make these shirts part of your sun protection system.
