This is one lap-top tote that won't tip over. Its polyurethane-coated 1,680-denier Ballistics fabric resists weather and abuse; the lining is 210-denier nylon pack cloth. Foam padding at the base and sides acts as a buffer for delicate equipment. The main compartment's \\"hinged\\" entry means that the pack stays open when needed; its zipper is water resistant. Slide the Commuter on to the extended handle of our Freight liners when you're running to catch the train. Imported.
