Great fit, simple style, and comfortable for all-day wear
Style: 7" Swim Trunk, Color: Aqua Blue, Size: Small
These swim trunks are a solid find—comfortable, well-made, and true to size. The 7-inch length is just right: not too long, not too short. They dry fairly quickly and have a mesh lining that’s supportive without being annoying. The style is simple and classic, and they’ve held up well through swimming, beach trips, and even some light hiking. Great value for the price.
