Warmth Without Bulk - thanks to dual-layer brushed interior
A soft, brushed inner layer traps air for insulation while the smooth outer layer moves moisture outward, helping fabric dry faster.
Keeps youngsters warm during cold-weather activity without requiring bulky layers, making movement easier during runs and practice.
Freedom of Movement - with 4-way stretch construction
Four-way stretch fabric stretches both across and along the grain, maintaining shape through dynamic motions and repeated flexing.
Allows comfortable sprints, stretches and play, while maintaining a close, streamlined fit that stays put.
Dry Comfort During Effort - thanks to fast-drying, moisture-wicking fabric
Polyester-dominant fabric wicks sweat from the skin to the outer surface where it evaporates more readily, reducing clinginess.
