Orvis' Sun Defense knit hoodie offers extra protection from the sun-from your waist to the top of your head. Designed to take on scorching, sun-filled days in cool comfort, the lightweight, moisture-wicking, quick-drying Sun Defense knit is rated UPF 50+ and treated with odor-blocking, eco-friendly OutSmart Fresh. Orvis was able to achieve a high UPF rating, while keeping the top lightweight and breathable, thanks to the use of Anti-NIR (Near Infrared Radiation) yarn, which reflects heat and protects your skin in a single jersey knit. Stretch binding around the hood keeps it in place around your hat or head. Comfortable thumb loops keep your sleeves down and provide extra coverage for your hands. Active fit.
