Circuit Line Swim Trunks are cut from our [FLOW] fabric and made for days spent tracing coastlines and chasing new breaks. Featuring a silky, anti‑chafe mesh liner and an adjustable drawcord waist, they deliver a secure, frictionless fit that keeps up from first plunge to last light. The 4‑way stretch silhouette moves easily on sand, rock, and in the water, while the UPF 50+ rating provides dependable protection under strong sun.
