Extremely lightweight and extremely warm, the Clam Ice Armor Fusion Liner Jacket is the ideal jacket for bumming around town on a cold winter day or zipping into an Edge or Lift parka. The Fusion's shell is constructed from 220T Taffeta, while the 3M Fill Power Thinsulate synthetic down lining keeps you super-warm and comfortable. Plenty of storage is found in the hand warming pockets and internal valuables pocket, all of which feature YKK zippers. Chest venting is also just a zip away when you get a little too toasty. Elastic cuffs seal out the elements and add another layer of comfort.
