Buying Guide

Prioritize UPF 50+ protection

Look for sunsuits with certified UPF 50+ fabric to block most UV rays rather than relying solely on sunscreen on covered areas

Check zipper and closure design

A full or long front zipper with a protective chin guard simplifies diaper changes and reduces irritation at the neck

Choose stretch and quick-dry fabrics

Blends with elastane or spandex improve fit and mobility while quick-dry materials reduce chill and ease diaper changes

Consider sleeve length and coverage

Long sleeves and higher necklines increase sun coverage; short-sleeve or legless options can be better for hotter climates or active wading

Factor in sizing and adjustable fit

Brands with toddler and baby size ranges and some stretch offer longer usable life and a better fit across growth spurts
