A two-layer fabric with an ultra-warm, brushed inside and a smooth, quick-drying outside. Stretch mesh panels in the armpits provide strategic ventilation without heat escaping. The 4-Way Stretch technology allows for better movement in every direction. The material wicks away sweat and dries very quickly. The ergonomic design prevents seams from forming in areas with a high degree of abrasion. Collared neckline for added coverage and warmth.
