Cover up—don't burn-up—in our ultralight UPF 50+ quarter-zip. Typically, the lighter the fabric the less sun protection, but not our jersey knit. New anti-NIR (near infrared radiation) yarn reflects heat and breathes to both cool and protect. Plus, it dries quickly, wicks moisture, and fights odors with OutSmart® Fresh, making it perfect for fishing, workouts, or going out-and-about town for the day. Integrated thumb loops keep the sleeves down for comfort under layers and create extra coverage for your hands. Polyester/spandex. Washable. Imported.
