Buying Guide

Check UPF rating

Choose shirts labeled UPF 50+ for consistent UV blocking during extended sun exposure

Prioritize fabric blend

Look for nylon/spandex or polyester/spandex blends that balance stretch, quick-dry performance, and durability

Consider fit and sizing

Select a snug but not restrictive fit and consult size charts for layering over swimsuits or under wetsuits

Inspect seam and cuff construction

Flatlock seams and elastic cuffs reduce chafing and help the shirt stay put during active play

Choose easy-care finishes

Fade-resistant colors and machine-washable fabrics maintain protection and appearance through frequent use
