Such backpacks are an excellent accessory with a lot of advantages. Uniform pressure on the shoulders removes most of the load from the musculoskeletal system. Hand luggage or a shoulder sports bag puts pressure on only one shoulder, causing the spinal column to bend. Backpacks, despite the seemingly small volume, have a large capacity. Even the smallest, thanks to the convenient location of pockets and compartments, is able to accommodate many items. I ordered a similar one using the Mato & Hash service
