Buying Guide

Choose the right fabric blend

Look for polyester/spandex blends for stretch, sweat-wicking, and fast recovery after intense gym sessions

Match compression to activity

Compression-style spats offer muscle support for grappling and conditioning, while lighter leggings prioritize freedom for running and drills

Check thermal rating for season

Cold-weather baselayers use thicker, brushed fabrics for insulation, whereas HeatGear-type fabrics aim to keep kids cool during indoor workouts

Prioritize fit and sizing range

Choose leggings with a wide size range and adjustable waist or elastic comfort to maintain fit through growth and movement

Inspect reinforcement and seams

Flatlock seams and reinforced knees/gussets reduce chafing and extend durability in high-abrasion training
