From first dives to lasting sunsets, the 7Diamonds take on swim trunks is here. Our four-way stretch nylon blend serves many purposes. Flexible, and quick to dry, it gives you complete freedom whether you are swimming laps, diving, or stretching out on the sand. A vented side opening gives you a more natural stride for greater range of motion. Inside, a boxer brief lining offers supportive coverage that feels secure and eliminates the discomfort of traditional mesh.
