Buying Guide

Prioritize UPF 50+ protection

Choose sunsuits with certified UPF 50+ fabric to block the majority of UVA/UVB rays for extended beach exposure

Look for full-coverage designs

Long sleeves and higher necklines reduce reliance on sunscreen by covering more skin during play and water time

Check sizing for growth

Opt for brands and cuts that accommodate baby-to-toddler transitions with stretch or slightly roomier fits to extend wear time

Assess closure and diaper access

Front zips or snaps that allow quick diaper changes and easy on/off are more practical for beach routines

Consider fabric and care

Look for chlorine- and salt-resistant blends that retain stretch and color, and follow care labels to preserve UPF performance
