Under Armour ColdGear Reactor Women's Insulated Run Gilet

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 a lightweight reactor technology, Under Armour ColdGear Reactor Run Gilet adapts to your activity level for optimum breathability and warmth. Dual-layer ColdGear fabric features an ultra-warm brushed interior and a smooth, fast-drying exterior to keep you cosy but dry when the temperature drops. Enriched with moisture-management technology, this top wicks sweat away from the skin for quick evaporation, so you stay damp-free and comfortable during intense exercise. A four-way stretch construction provides a full, unrestricted range of motion ensuring you can get the most out of your workout. Woven overlays on the chest provide added durability and protection and allow for a tighter fit that hugs the body and moves as you do. A dropped hem provides added coverage whilst secure zip hand pockets provide ample storage for essential items. Lastly, reflective details ensure visibility to passing vehicles of late night runs.
