I purchased this as a domestic genuine product at the regular price about 10 years ago. I only used it a few times in the first year. Due to long-term storage, there is some discoloration on the storage cover. Perhaps because it hasn't been used for a while, the upper compression strap is a little sticky. There are no problems with use. The exterior is also in beautiful condition, and there are no scratches inside. The seam is also solid. Capacity: 26 liters Weight: 310g Size: 50X27X15cm Material: 100D Cargo Chute Nylon Features: This is a lightweight and compact summit pack that also serves to store a sleeping bag. Lightweight and durable cargo chute fabric. 3-point compression system for compacting sleeping bags / with two tool loops. Zippered pocket on the rain cover. There is a zippered pocket inside the main body that also serves as a storage bag. Outdoor backpack with adjustable shoulder straps and zippered pocket. Thank you for viewing. I have other items for sale. Thank you.
