Buying Guide

Prioritize UPF rating

Choose rash guards labeled UPF 50+ to block UV rays and reduce reliance on sunscreen for covered skin

Check sleeve length

Long sleeves offer more sun coverage for pool and beach days, while short sleeves increase breathability for warm climates

Look for stretch and fit

Soft, four-way stretch fabrics and snug but not constricting fits let babies move comfortably and layer under swimwear

Assess care and durability

Pick materials that withstand chlorine and saltwater exposure and tolerate machine washing without losing shape

Consider sizing and growth

If between sizes, size up for longer wear or choose toddler-specific cuts labeled for baby/toddler ranges to accommodate growth
