The Giro Women's Roust Boardshorts are perfect for those days when you want to surf the loam. They feature a tie waistband closure and a simple silhouette in a lightweight stretch fabric. But don't confuse lightweight with delicate! The Roust Durablend material increases the spandex content (85% nylon / 15% spandex) for a material that is lightweight, stretchy and durable. It even has a Durable Water Repellent (DWR) coating and a UPF 50+ rating.
