Buying Guide

UPF rating matters

Look for UPF 50+ fabrics to maximize ultraviolet protection during extended outdoor or water play

Fabric and stretch

Choose blends with nylon or polyester and spandex for quick-drying performance and enough stretch for swimming and movement

Seam and collar construction

Flatlock seams and a comfortable collar reduce chafing on wet skin, especially for active kids

Fit and sizing

Select a snug but not restrictive fit—many rash guards are designed to be close to the body to prevent drag and rubbing

Care and durability

Follow care labels for chlorine and saltwater exposure; durable colorfast fabrics and reinforced stitching extend garment life
