O'Neill Girls Rash Tee Slim Fit Capsleeve Rashguard Swim and Surf Shirt 50+SPF 91% nylon/9% elastane Finally, a rash guard for Girls that has a looser, more comfortable fit than traditional rash guards! So much better than a t-shirt over a swimsuit, rashguards 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. Designed to be worn over a swim suit, with boardshorts, or as casual wear, this rash tee is made of the same 6 oz. lycra as O'Neill's popular skins series of rash guards. Though it still has the same 50+ UV Protection factor to protect you from harsh rays, it is sized so that if you choose your regular clothing size, it will have a little room to spare and not be skin-tight. Fast-drying, odor-resistant, flat-loc stitched with breathable seams.
