Buying Guide

Check UPF rating

Look for UPF 50+ labeling to ensure the fabric blocks a high percentage of UV rays during extended sun exposure

Prioritize fabric and stretch

Choose blends with smooth, quick-drying performance and four-way stretch for comfortable movement in water and on land

Consider fit and sizing

Rash guards should be snug but not constricting; review size charts and look for options that accommodate layering if needed

Inspect seams and construction

Flatlock or reinforced seams reduce chafing and improve durability for active use and frequent washing

Look for reputable brands

Brands with consistent customer ratings and repeated UPF listings—such as RuggedButts—tend to combine reliable protection and value
