This is a carrying porter for KAVABORG guitar hard cases. ■ Carrying Porter for Guitar Hard Cases ■ Case Saddle The Kavaborg CASE SADDLE is a daypack-style attachment ergonomically designed for comfortably carrying hard cases. You no longer need to use your other hand to carry a hard case that only has a handle and no straps. You can carry guitar cases, bass cases, and even viola cases on your back, freeing up both hands and making travel more comfortable. The CASE SADDLE's RELAX-ON is a system created using ergonomic design, designed to reduce the weight of the hard case from being placed solely on the shoulders and to support the hard case with the entire body. Furthermore, it is highly breathable, preventing stuffiness even in summer. The use of strong and safe buckle materials allows for safe carrying of hard cases. The CASE SADDLE's fiber ribbon is made of a material that can withstand a tensile force of 200 kg. It is strong and tear-resistant, so you can use it for rough travel. By incorporating 10mm thick sponge, it firmly supports the back even during long journeys.
