Buying Guide

Check UPF rating

Choose sunsuits with a verified UPF 50+ rating to ensure maximum fabric-level UV protection for sensitive baby skin

Prioritize full coverage

Long-sleeve, high-neck designs and integrated leg coverage reduce sun exposure more effectively than two-piece options

Look for easy closures

Front zippers or snaps simplify diaper changes and dressing at the pool or beach; reinforced zippers resist salt and chlorine

Consider fabric and care

Lightweight, quick-drying blends with chlorine resistance hold up better over time and are easier to launder after frequent use

Size for layering and growth

Select a size that allows for a snug fit for UPF performance but accommodates layering or a growth margin through the season
