Buying Guide

Prioritize UPF protection

Choose swimsuits labeled UPF 50+ to block most UV rays and reduce sun exposure for delicate baby skin

Consider sleeve length

Long sleeves add coverage and extra sun protection, while short sleeves or sleeveless styles are cooler for active beach play

Check fit and fastenings

Look for a snug but flexible fit with secure closures or stretch fabric to prevent shifting during swimming and movement

Evaluate fabric and care

Select chlorine- and salt-resistant blends that dry quickly and list easy-care instructions to keep colors and stretch longer

Balance size and growth

If between sizes, opt for a slightly larger size with adjustable features to extend wear without compromising fit
