The Condor Core Vest was designed for daily use to keep your vitals warm during cooler weather or climates, as well as colder seasons. Micro-fleece lined interior ensures warm active comfort. The lower cut arm holes are designed give the user greater mobility and ventilation in contrast to the SUMMIT or PHANTOM jackets. The Core vest is great for the outdoors with its breathable film membrane and Teflon coating. It's made with 4-way stretch high-density fabric to stop the wind, and is equipped with interior and exterior zipper pockets to carry essential items.
