The Kappa RB105R is a retro-styled single-side bag that doubles as a stylish backpack. It features a 17-litre volume and is made from 470 Denier recycled nylon in dark green; it features a non-removable waterproof 70D 190T nylon inner lining undyed to conserve water resources, preventing the release of run-offs from dyeing into the groundwater and saving the energy that would be required for the process. It has non-slip fabric on the back and a system of fixed plastic hooks that allow fixing to Kappa TMT_K and TE_K frames. It has a roll-top closure with hook and loop fastening, a front pocket, a front handle and straps to wear this as a rucksack. A lower strap allows attachment to the frame, and it has a front M.O.L.L.E. system. Measures 40cm x 15 cm x 28 cm.
