Got lots of gear, but don"t need an Air Case to ship it? Get a Car Case! Just as easy to carry as an Air Case but more affordable, plus a lighter construction. A three tier sandwich construction composed of an outer shell of tough ballistic nylon, a lightweight sheet of air channel polyethylene to disburse shock and 1/4-inch thick, closed cell, cross linked, 2 lb. density enbazoate foam to absorb shock. Lined with smooth 400 Denier nylon pack cloth for a smooth appearance and to further protect the foam from wear and tear of sharp contents.
