The ColdGear Infrared Alpinlite Jacket is packed with cozy PrimaLoft insulation - 100 grams in the body, 60 grams in the sleeves - for exceptional 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. The ColdGear Infrared Alpinlite Jacket features a stylish, all-over quilted pattern; mock-neck collar; full-length front zipper; ColdGear cuffs; and secure hand pockets with an internal headphone escape. The jacket packs into its own pocket for easy transport. 100% polyester fabric. Semi-fitted design. Imported.
