Designed for anglers on those hot sunny summer day. The Aquacamo collection is with an SPF/UPF 50 light weight fast drying breathable fabric. We specifically designed this shirts pattered to hide you from the fish you are targeting. 7 out of 10 Mermen said they could not see us at all and only 3 of them were blind. So we feel like this is an amazing shirt for you the angler.
