Story
Part swim trunk, part active short—now in an exclusive Realtree® Aspect water camo
To celebrate the summer season, we worked with our friends at Realtree® on this exclusive Aspect® water camo: A photorealistic print inspired by the ripples of the lakes and rivers we swim here in Austin. The print here lives on our bestselling Performance Lined Swim Trunk. 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 two shorts in one, making it our pick for all-day adventures in and out of the water.

- Exclusive Realtree Aspect® water camo
- Athletic fit with a comfortable waistband
- Ultra-soft AC Liner™ approved by elite triathletes
- Mesh-lined side pockets with hidden AirPods sleeve, a back snap pocket with an embedded key bungee, and a new hidden side zip pocket
