Buying Guide

UPF rating matters

Choose sunsuits labeled UPF 50+ to cut UVA/UVB exposure and reduce the need for constant sunscreen reapplication on covered areas

Look for secure closures

A front or back zipper with a protective placket speeds diaper changes and prevents skin pinching during movement

Prioritize fit and range of motion

Select suits with a bit of stretch in the fabric so babies can kick and reach without the suit riding up

Consider fabric weight and drying time

Lightweight, quick-dry polyester blends stay comfortable for pool play and reduce chafing when wet

Check care and durability

Pick suits labeled chlorine-resistant or with reinforced stitching to retain color and shape after repeated swims
