Eberlestock Gossamer G-Type Frame Short Black. The interchangeability of these two frame types fulfills the Intex II modular concept. The basic design of packs equipped with the Intex II is intended to take advantage of the Eberlestock Gossamer Backpack Frame's superior support comfort and load-bearing interface with the human body. But there are times when you may want a flatter or more compressible pack or a more flexible overall structure and it is for these reasons that we've developed the frame. Made of polycarbonate with vertical-axis stiffening channels the frames of these Carrying Bags provide an ideal mix of vertical support and torsional flex. They are quite tough and are superior to polyethylene frame-sheets which form the core structure of most internal frame packs. Thus the Eberlestock Gossamer G-Type Frame is a simple and high-performance means to convert your Intex-II equipped pack to a more traditional internal frame pack.
