Super-Soft Nylon and High-Stretch Spandex Deliver All-Day Protection Without Sacrificing Style. Headlining SCUBAPRO's new UPF Collection of rash guards, steamers, leggings, bikini cut shorties and loose fit tops, T-FLEX leggings are designed to make a statement while providing the ultimate in comfort and protection before, after and during the dive. Flattering T-FLEX leggings look great, plus make donning a wetsuit oh-so-easy when worn as an under-layer. They are the perfect complement to all the rash guards in the UPF collection. When worn under water they protect against stings and abrasion, and when worn on the surface they provide a level of UV protection unmatched in the industry.
