On chilly early-morning runs you need to wear some head protection to keep you warm, but when you wear a hoodie and your neck gaiter you often feel suffocated as you run. Under Armour created the CG Reactor Run Balaclava Pullover Hoodie to solve this issue. By combining the hoodie and the balaclava you get no-fuss comfort. ColdGear Reactor technology manages body heat and breathability for optimal performance. And while the moisture-wicking and quick-drying properties work to keep you dry, anti-odor technology manages unwanted odor-causing microbes. Brushed internal material is soft on the touch and hugs the body like second skin for a fitted feel to keep you warm all season.
