Omni-Heat technology gives this traditional half-zip pullover a hearty helping of lightweight heat so you can tackle trails without the burden of bulky layers. A thermal reflective layer is printed directly onto the back of the fabric to reflect and retain your own body heat, resulting in 20% more warmth for you. Rock the Heat 360 alone or layer it under your favorite shell for the perfect heat-regulating mid-layer. Hybrid fabric technology - combining a 93% polyester, 7% elastane Heat microfleece shell and 92% polyester, 8% elastane Heat Thermo Stretch panels - offers four-way comfort stretch so it moves with you, and breathes easily to keep you comfortable. The half-zip front placket allows for controlled ventilation and helps prevent overheating. A zip-closed security pocket at the left chest stows energy bars, cash, keys, and other essentials. Active fit. Imported.
