Buying Guide

Check UPF rating

Look for UPF 50+ or equivalent labeling to ensure reliable UV protection during extended sun exposure

Prioritize sleeve length

Long sleeves provide better coverage for shoulders and arms, which reduces sunscreen reapplication needs

Consider fabric and stretch

Lightweight, quick-dry fabrics with four-way stretch improve comfort and allow freedom of movement for swim play

Verify size and fit options

Choose brands that list chest and height measurements or offer toddler through older-kid sizing to avoid returns

Look for flat seams and tagless labels

Flatlock stitching and tagless designs minimize chafing and irritation during active water use
