Collection: Bikinis

Designed with surf and swim in mind, arena’s bikini collection for women carries versatile pieces perfect for days spent under the sun.
Ranging from fitness fabrics ideal for training, to casual designs for beach-side lounging, the internal lining and shapely seaming are sure to flatter and support your body.
Mix and match bandeaus, tankinis, tie-backs or triangle cuts for your top, and varying coverage levels for your bottoms.
