Buying Guide

Prioritize UPF protection

Choose shirts labeled UPF 50+ to block the majority of UV radiation during extended outdoor water play

Check fit and sizing

Look for snug but comfortable fits with stretch fabric and size guides that account for layering and growth

Assess fabric and stretch

Prefer nylon/spandex or polyester/spandex blends for chlorine resistance, quick-dry performance, and mobility

Inspect seam and cuff construction

Flatlock seams and reinforced cuffs reduce chafing and wear from repeated splashing and washing

Consider care and durability

Machine-washable, colorfast fabrics maintain UPF and appearance after frequent use and exposure to sun and pool chemicals
