Cruising the SUP from harbor to kelp forest means all-day sun exposure- easily handled by the Long-Sleeved Silkweight Rashguard. The full-coverage sun shirt is made from a lightweight blend of 94% polyester (35% recycled) and 6% spandex with 50+ UPF sun protection and Polygiene permanent odor control. Rib-knit collar for easy on/off. Straight sleeves feature angled side panels that extend through to eliminate underarm chafing. Slight drop-tail hem for additional coverage. Flying fish graphic on center back.
