Under Armour ColdGear Reactor Run Funnel Neck Women's Top

We've solved the problem of being too cold when you start running or too hot when you get going. ColdGear Reactor actually adapts to what you're doing by dumping heat as you pick up speed.

Constructed using ColdGear technology the Under Armour Fitted Mock Neck Top works to keep you comfortable and warm on cold weather days. The generously warm, fast-drying interior helps you to stay warmer for longer by absorbing and retaining your own body heat when the mercury drops. ColdGear Reactor is a lightweight, intelligent insulation that adapts to your activity level for the right breathability and warmth for what you're doing. This innovative technology keeps you as warm as possible when there is little to no movement, but as soon as you get moving and the blood starts pumping, the technology works to dump that excess heat that is not needed anymore. The top feature a moisture-managing system which works to wick excess sweat and moisture away from the skin to keep you comfortable and dry during intense workouts. The next-to-skin fit ensures a snug and supportive fit without the squeeze plus, a dropped hem provides added coverage so you'll always feel comfortable and supported. A generous funnel-neck collar offers a built-in mesh face mask for extra protection and coverage when you want and need it. Asymmetrical tibto cuffs offer extra wrist and hand coverage for those bitter days, while thumbholes keep the sleeves from riding up the arms and keep the heat in. Lastly, reflective details increase your visibility to passing vehicles on late night adventures.
