Our Beach Series Long Sleeves are a soft comfortable long-sleeve tee shirt for adventure or daily wear. Quality construction purposefully designed fabric superior to a typical tee. LIGHT, SOFT COMFORTABLE: 4.1oz. Microfiber fabric feels super soft and moves with you but won’t cling or stretch out. Zinc-based technology fights odor to help you stay fresh. MULTI-USE MULTI-SEASON: This long-sleeve shines in the summer as a sun-protection shirt or swim shirt with its permanent built in UPF 50 UV protection. In colder weather, it’s an excellent base layer for wicking and warmth without adding bulk. Working out, hiking, biking… countless hours of outdoor adventure, play, and work are logged in our shirts.
