Buying Guide: How to Choose the Right Rash Guard
- What level of sun protection do you need? Look for UPF ratings of 50+ for strong sun exposure, especially during summer at the beach or on open-water activities.
- What activity will your child primarily do? For water sports, prioritize quick-dry and moisture-wicking fabrics; for martial arts, consider non-slip edges and durable stitching.
