Buying Guide

Prioritize UPF protection

Choose swimsuits labeled UPF 50+ to block a high percentage of UV rays and reduce sun exposure on delicate skin

Look for full-coverage designs

Long sleeves and high necklines provide extra coverage for shoulders and chest, limiting the need for constant sunscreen reapplication

Check closure and zipper placement

Front zippers or snaps make diaper changes and dressing easier; a zipper guard prevents irritation at the chin

Prefer quick-dry, stretch fabrics

Nylon/spandex blends or polyester with good stretch help with movement, quick drying, and comfortable fits for active babies

Consider size range and fit

Select brands with baby-to-toddler sizing and read fit notes; slightly roomier fits accommodate diapers without restricting movement
