Buying Guide

Prioritize UPF 50+ protection

Choose sunsuits that specify UPF 50+ fabric to block most UV rays and reduce reliance on chemical sunscreens for covered areas

Check closure and zipper placement

Front zippers or zip closures that extend past the torso make diaper changes and on/off easier for caregivers, especially with wriggly infants

Look for long-sleeve options

Long-sleeve sunsuits increase covered surface area, offering more sun protection and warmth for cool pool or beach days

Assess fabric weight and stretch

Lightweight, quick-drying blends with good stretch improve mobility and comfort while swimming or playing

Consider size range and fit notes

Brands with clear sizing and baby-to-toddler ranges help ensure a better fit across growth spurts and reduce the need to size up excessively
