Mountain Hardwear Ramesa Short 100% Nylon Gusseted crotch construction gives the shorts extra room at the seat and allows the wearer extra flexibility despite the nylon-poly fabric's non-stretchy quality. Mesh pockets allow water to drain away easily after a swim, and pockets' flat seam construction gives the Ramesa shorts a low-profile appearance while retaining easy access to the interior of the pocket. UPF 50 fabric gives the wearer maximum protection from the sun during the long summer days, blocking an estimated 98% of UV rays. The Ramesa women's shorts are made from water-resistant nylon and polyester, allowing for rapid drying after summer fun in the water. The Ramesa shorts feature a built-in nylon webbing belt, which adjusts quickly and easily and fastens with a durable plastic buckle.
