Buying Guide

Liner type matters

Choose trunks with a compression or boxer-brief liner for added support and comfort during active play; several options here include either compression liners or boxer-brief liners

Look for UPF or sun protection

Swimwear with UPF-rated fabric helps reduce sun exposure; some styles in this price band list UPF 50+ protection for extra coverage

Prioritize quick-dry fabrics

Quick-dry materials reduce chafing and odor between swims—many affordable trunks use lightweight, breathable fabrics designed to dry faster

Check fit and size range

Pick trunks that offer the child's size and room for layering; children’s swim lines here span toddler to big-kid sizing to accommodate growth

Evaluate construction and washability

Look for reinforced waistbands, secure drawstrings and machine-washable fabrics to keep trunks holding shape and color through repeated use
