The 50+ UPF Oysterman shirt is the perfect combination of simplicity and functionality. With two hidden zipper pockets up front, snag/rust proof athletic plastic snaps including under collar points. With a hidden sunglass cleaner, it seems over loaded with features, but don't worry, you won't even notice them until you need them. You also won't notice the all over perforations in our Airmesh fabric until a light breeze cools your whole torso while standing on the bow, comfortably in 98 degree heat and high humidity. This is the future of fishing shirts.
