Built for beach days that turn into all-day plans.

• Quick-drying, lightweight fabric

The Opa swim trunks are made for the kind of days that don’t follow a schedule, beach in the morning, drinks in the afternoon, wherever the day goes after that.

The lightweight quick-dry fabric keeps you comfortable in and out of the water, while the silky anti-chafe inner liner helps eliminate irritation so you can actually wear them all day. Finished with a bold BAS print, these aren’t just swim trunks, they’re part of the vacation fit.
