Buying Guide

Check UPF rating

Choose shirts labeled UPF 50+ for reliable ultraviolet protection during extended sun exposure

Prioritize fabric stretch

Look for high-stretch knit blends for comfortable movement, especially for active swim and play

Consider sleeve length

Long sleeves provide more skin coverage and sun protection, while short sleeves offer cooler wear for warmer days

Review size range

Pick a brand offering multiple sizes from baby/toddler through older kids to ensure better fit and layering

Inspect care and durability

Opt for fabrics that keep shape and UV performance after washing to maintain protection season after season
