Buying Guide

Prioritize UPF rating

Choose rash guards with UPF 50+ to block the majority of UV radiation and reduce reliance on sunscreen for covered areas

Check size and fit guidance

Look for brands that offer baby and toddler sizing with stretch fabrics so you can pick a snug but comfortable fit that doesn't ride up during play

Opt for quick-drying, stretchy fabrics

Nylon-spandex or polyester blends dry faster and retain shape after swimming, improving comfort and reducing chafing

Look for long-sleeve options for extra coverage

Long sleeves increase sun coverage on arms and can be layered under swimsuits or wetsuits for variable conditions

Weigh value vs. brand consistency

Consider brands with consistent UPF claims and high customer ratings to balance cost and reliable sun protection across sizes
