Thank you for viewing. This is a backpack I used for mountain climbing a while ago. The adjustment component on the right strap is broken (images ⑤-⑥). I have kept it stored at home without using it, so I took it out and washed it once. The size is approximately 50 x 50 x 25cm when laid flat. It's made in China and I believe the fabric is thin nylon. I will fold it for shipping. Please understand that this is a used, aged, and home-stored item before purchasing.
