Buying Guide

Prioritize UPF and sun protection

Look for UPF 50+ fabrics and long-sleeve rash guards to reduce UV exposure during extended outdoor play

Check fabric and stretch

Choose blends with nylon or polyester and spandex for quick-dry performance and shape retention after repeated wear

Match fit to activity

Opt for long-sleeve sets or higher-coverage styles for active water play and two-piece styles for lap swimming or beach lounging

Consider sizing and growth

Select adjustable or slightly roomier fits and consult size charts to accommodate growth and layering under rash guards

Inspect construction details

Reinforced seams, secure closures, and lining in bottoms improve durability and comfort in chlorine and saltwater
