The SUNWT Shirt collection is constructed from lightweight microfiber polyester with quick dry technology. The fabric offers a bit of stretch and feels like silk next to skin. This shirt protects you with 35+ UPF sun protection every minute you wear it. Our SUNWT Shirts are also effective base layers when conditions get cool. For the Colorblock Jersey we've incorporated multiple colors from our palette into a one-of-a-kind shirt design that is distinctly TWELVE WEIGHT. Make the SUNWT Shirt part of your sun protection system for fishing, hanging at the water or for everyday use.
