Performance Lined Swim Trunk - 5"
Story
Our favorite swim trunk and all-day active short—now in an exclusive design by an Austin artist
We teamed up with artist, local Austin legend, and longtime friend Will Bryant to bring a new spin to our bestselling Performance Lined Swim Trunks. The inspiration for this limited edition print came easily. Will wore his favorite vintage Hawaiian shirt (that he stole from his dad) to our brainstorming session, and the design started flowing. The result is the perfect nod to throwback tropical patterns—infused with Will’s signature touch and printed on the most comfortable swim trunk on the market. Add in 4-way stretch, an ultra-soft, DryWetDry™ Liner, hidden pockets, and a modern fit, and you’ve got a half-performance short, half-swim trunk hybrid that looks as good out of the water as they do in the deep end.
