【! Junk Item!】 This is a Montbell waist bag. The current model that's closest to it would be the "Trail Lumber Pack," I think. It's a bag designed to firmly secure your belongings to your waist to prevent them from shifting while running or hiking in the mountains. ★ The zipper on the main compartment does not open! There is rust, and one of the zipper pulls is broken. The zipper itself seems to be a water-resistant type and appears sturdy, but the pull seems to have given way first. ★ There is overall soiling! There are white stains that look like mold and scratches. ★ The plastic parts seem to be intact. I thought the plastic would deteriorate over time, but I tested the buckles repeatedly, and they work fine. ★ The cushioning on the waist belt also seems to be in good condition. If you think you can repair it yourself, or if you want to use it for parts, please feel free to take it.
