The Under Armour ColdGear Infrared Alpinlite Max Jacket is packed with ultra-cozy PrimaLoft insulation - 400 grams in the body, 200 grams in the sleeves - for unparalleled warmth and comfort in even the coldest conditions. Under Armour's revolutionary ColdGear Infrared Technology utilizes a soft, undetectable ceramic-coated print on the interior of the garment which seeks out, absorbs, and retains your own body heat. The result? You stay warmer for longer without excess weight or bulk. The UA Storm DWR finish repels water without sacrificing breathability. Raglan sleeve construction allows for a full range of motion in the arms. The ColdGear Infrared Alpinlite Jacket features a mock-neck collar; full-length front zipper; ColdGear cuffs; zip-secure hand pockets with interior hem adjusters; and a secure audio pocket at the left chest. Shell: 100% nylon fabric. Lining/Insulation: 100% polyester fabric. Loose fit. Imported.
