Two shorts in one, this is our pick for all-day adventures in and out of the water. Built from a quick-drying four-way stretch fabric with an ultra-soft liner approved by elite triathletes, it can power everything from laps in the pool and longboard sessions to beach workouts and the bike ride back to the lakehouse. It offers UPF 50+ protection from the sun, fast-draining mesh pockets, and hidden sleeves for stashing your essentials. It’s Wellen's bestselling trunk, newly updated for Proof.
