The O'Neill surf tee is lightweight and breezy, yet keeps harmful rays away from your skin with 50+ UV protection factor. With a left chest pocket and colorblock design, this version of the surf tee can be worn any day of the week - not just for surfing. The slim fit (looser than traditional compression-fit rashguards, yet narrower in the chest and waist than casual t-shirts) lets you move through the water without excess fabric dragging you down but is a bit more merciful than a rashguard. So much better than a t-shirt over a swimsuit, surf tees can be worn in and out of the water. The lightweight yet dense weave dries quickly, breathes and keeps cool, yet blocks out harmful sun rays.Note: These shirts are sized to fit like a slim fit t-shirt: not as tight as a traditional rashguard, but not as loose as regular clothing. If you prefer a looser fit, order up a size or two. Designed to be worn over swim trunks, with boardshorts, or as casual wear. Slim-fit cut combined with quick-dry, four-way stretch properties for all-day comfort. One chest pocket with inner key loop Heathered 5 oz. weight fabric (93% polyester, 7% elastane) with overlock seams 50+ UV Protection factor to protect you from harsh rays.
