Buying Guide

Prioritize UPF 50+ protection

Choose sunsuits labeled UPF 50+ to reduce UV exposure; multiple options in this list include certified UPF 50+ fabrics for consistent sun protection

Look for full-coverage designs

Long sleeves and higher necklines or front zips provide more skin coverage than standard swimsuits, which helps limit sunscreen reapplication during pool time

Check zipper and closure placement

Front zippers ease dressing and diaper changes—verify a protective zipper flap or guard to prevent skin pinching and minimize water entry

Assess fabric stretch and fit

Soft, stretchy blends that hold shape give a snug but comfortable fit for active babies and help maintain UPF performance when wet

Balance price and durability

Expect midrange pricing for UPF-rated sunsuits; consider options with higher customer ratings and durable stitching to maximize value over multiple seasons
