A full day on the water — whether that's fishing, boating, or moving between both — demands a shirt that can keep up with all of it without needing to be changed between activities. The construction matters: stretch fabric that doesn't restrict casting, breathability that handles open-water heat, and a cut that still looks intentional once you're back at the dock. Psycho Tuna builds its button-up shirts around that kind of all-day usefulness, making them one of the more practical pieces in a coastal wardrobe.
