Buying Guide

Prioritize UPF rating

Choose rash guards labeled UPF 50+ to ensure high fabric-level protection from UV rays during sun exposure

Check fabric and stretch

Look for blends with nylon, polyester, or spandex for quick-drying performance and enough stretch for comfortable movement while swimming or playing

Prefer long sleeves for more coverage

Long-sleeve designs extend sun coverage over arms and shoulders, reducing the need for constant sunscreen reapplication on those areas

Evaluate fit and sizing

Select sizes that allow a snug but not restrictive fit—rash guards should fit close to the skin to work effectively without limiting reach

Assess care and durability

Fabrics that tolerate chlorine, saltwater, and machine washing will maintain UPF properties and print quality longer for toddler wear
