Buying Guide

Prioritize UPF rating

Look for fabrics labeled UPF 50+ to block the majority of UVA/UVB rays and reduce the need for constant sunscreen reapplication on covered areas

Check fabric and stretch

Choose blends with nylon or polyester and elastane for quick-drying performance and comfortable stretch that holds up to active toddlers

Pay attention to fit and sizing

Opt for slightly roomy or size-adjusted options to allow layering and freedom of movement; many toddler swim shirts run small across shoulders

Look for long sleeves and secure closures

Long-sleeve designs provide extra coverage; features like tagless labels and flat seams reduce irritation on sensitive baby skin

Evaluate durability and care

Select garments with reinforced stitching and easy-care instructions (machine wash, quick dry) so sun-protective benefits persist through frequent use
