1.100% Polyester 2.Omni-Heat Thermal Reflective 3.Omni-Tech Waterproof/Breathable Critically Seam Sealed 4.Removable, Adjustable Hood 5.Waterproof Zippered hand pockets 6.Imported Built with innovative zero-bulk construction for freedom of movement and Pro fabric for the highest level of durably waterproof/breathable and windproof protection. The construction of 3-Layer Products is unique. A 3-layer membrane is sandwiched between a soft outer material and a knit polyester backing material that increases durability. These garments keep you comfortable and protected from the elements without adding extra bulk or weight. The Pro membrane has 4 billion pores per square inch, with each pore 10,000 times smaller than a water droplet. These tiny holes are too small for water and wind to pass through from the outside. But these same pores are large enough for moisture vapor to pass through, so your body\'s perspiration is able to escape and you won’t feel clammy or uncomfortable inside your jacket.
