The Simms Sunsleeve is a great way to provide additional sun protection on the river without needing to reapply sunscreen. Made of stretch fabric that boasts a 50+ UPF rating, the Simms Sunsleeve easily sildes over the arm and is secured with elastic at the bicep and a curved cuff at the wrist. Keeping you cooler than a traditional long sleeve shirt, the Simms Sunsleeve has the advantage of also being breathable and quick-drying. And when the sun goes down, all you need to do is pull off the sleeves and you're ready for a post fly fishing beer.
