Buying Guide

Prioritize UPF and sun protection

Look for swimsuits labeled UPF 50+ or long-sleeve rash guards to reduce UV exposure during extended outdoor play

Choose performance fabrics

Select blends with nylon/spandex or polyester/spandex for chlorine resistance, quick-dry performance, and long-term stretch retention

Consider sleeve length and coverage

Long-sleeve sets provide more sun protection and body coverage while traditional two-piece styles offer easier on/off for potty training

Check sizing and fit guidance

Review size charts and customer fit notes—many kids’ swim sets run small or are designed for layering under rash guards

Inspect closures and seams

Flatlock seams, secure waistlines, and non-irritating tags or linings improve comfort and durability for active children
