Buying Guide

Prioritize UPF 50+ sun protection

Choose shirts with a UPF 50+ rating to block the majority of UV rays during extended beach exposure

Check fabric blend and stretch

Look for polyester/spandex or nylon/spandex blends that balance quick-drying performance with enough stretch for active play

Consider true-to-size fit and length

Long-sleeve coverage matters—pick sizes that provide full arm coverage without restricting movement or riding up when wet

Evaluate seam construction and durability

Flatlock seams and reinforced stitching reduce chafing and hold up better through frequent wear and washes

Balance price and uniform value

For beach wear, prioritize durable UPF-rated pieces that offer consistent customer ratings around 4+ stars while staying within budget options under $50
