Skooba Design Superbungee Strap Case for Laptops (730-202) Same incredible strap that's standard on Skooba Satchel 2.0 and Skooba Seventeen 2.0 laptop bags, available seperately to "upgrade" just about any other bag, suitcase, sports duffel, etc. Patent-pending Skooba Superbungee Strap features "sport-tuned suspension system," consisting of a high-density, floating bungee/shock cord ring which acts as a shock absorber, minimizing carrying shock and perceived weight. Flexible grid of individual, air-filled cells to further enhance carrying comfort on the reverse (wearer) side of the contoured shoulder pad. Cells are covered in a friction laminate, to help keep even the heaviest bag from slipping.
