Fit & sizing
Cut in sizes XS to XL on real bodies, with supportive cups and full front lining. Between sizes? We suggest sizing up for a relaxed beach fit or down for extra support in the water.

Chlorine and salt-resistant knit with recycled fibers. Rinse in cool water after swimming and dry in the shade to keep colors bright season after season.

Good to know

Does it stay put while swimming?
Yes — the secure back and compressive lining keep everything in place through dives and turns.
