Buying Guide

Check UPF rating

Choose a rash guard labeled UPF 50+ or with documented sun-protection fabric to reduce UV exposure during extended outdoor use

Prefer long sleeves for coverage

Long-sleeve styles provide more skin coverage at the arms and shoulders, which is key for beach and pool days

Look at fabric and stretch

Seek nylon/spandex or polyester/spandex blends and UA-knit or similar constructions for quick-drying, flexible wear

Prioritize size and fit

Rash guards should fit snugly without compressing; review sizing guides to allow for layering and growth

Inspect seams and construction

Flatlock seams and reinforced stitching reduce chafing and increase durability for frequent water use
