Los Sony los compré de segunda mano por 250 euros. even with plastersmaybe I shall use them at my health club. I have an infiniti G37 - sedan, and looking at the racks systems for $300+ was not worth it. Size numbers are different than other brands. This piece i didnt feel flowed nicely, it was all bunchy, and the waist band was way to small unfortunately :( Not as convenient but already feels like a far better design for looking after your airpods pro. They fold nicely for the range bagNRR is 23 which is fairly decent for these type. Very light wight, with soft leather. Whatever you put down there make sure it is light or else it pulls on the fabric and will eventually rip it. It is somewhat stiff, although it still bends because of the accordion construction.
