This Hurley tee was designed for fun under the sun. It is made of soft double knit jersey fabric enhanced with quick-drying, moisture-wicking H20-DRI technology so you can run around or take it easy without getting too sweaty and sticky for ultimate comfort. Additionally, the fabric has a UPF 50+ finish to help protect you from the sun's harmful UV rays, thus making this tee a great sidekick to your favorite sunscreen and the long sleeves add extra protection (UPF protection is only guaranteed for skin covered by the tee. Apply sunscreen on skin that is exposed to the sun).
