Designed for spring, fall and deep winter wear, the Under Armour Coldgear Infrared 3-in-1 Furley Jacket will keep you warm, protected and looking good. This 100% polyester softshell jacket contains a fleece liner jacket, along with ColdGear Infrared technology. ColdGear Infrared technology is a result of Under Armour using infrared imaging to research and pinpoint heat loss in insulation systems, in an effort to make their gear warmer. Stealth Bombers stay undetected by utilizing a high-tech ceramic coating that absorbs electromagnetic waves, keeping heat in, rather than dispersing it into the atmosphere. Mimicking this technology, Under Armour was able to create a flexible ceramic coating on the inside of the garment that holds heat better rather than dispersing it, keeping you warmer longer. The waterproof/windproof/breathable membrane ensures that you stay warm and dry in the nastiest of conditions and that excess internal moisture is released into the atmosphere and away from you. The DWR water repellent treatment will keep you dry in mist and light rain, while the removable hood allows you to customize this jacket for the conditions. The fleece liner jacket features Signature Moisture Transport technology, wicking excess moisture away from your skin, keeping you dry, warm and comfortable.
