Buying Guide

Prioritize UPF protection

Choose sunsuits with certified UPF 50+ fabric to block ultraviolet rays for sensitive baby skin

Check fit and sizing range

Look for brands offering baby-to-toddler sizing and a snug but flexible fit to prevent ride-up while allowing movement

Evaluate closures and zippers

Front zippers or snap closures make diaper changes and dressing easier, especially on the beach

Consider fabric and quick-dry

Select chlorine- and salt-resistant materials with a soft lining that dry quickly to reduce chafing and irritation

Assess coverage and layering

Long sleeves, higher necklines, and optional swim hats or leggings increase overall sun protection on exposed areas
