Large-capacity, ergonomic design backpack with a mesh back panel and adjustable straps. - Brand: GREGORY - Model Name: ZULU - Color: Halo Blue - Back Panel: Mesh - Straps: Adjustable - Storage Space: Large Capacity - Design: Ergonomic Retail Price: 35,200 yen (tax included) Please see photo 6 for detailed size information. Purchased in September of this year. Used only once for a short time with a cover, so there are no stains or scratches. It fits very well and is easy to use because you can adjust the size to fit your body in various places, but I am selling it because I already have a 40L one. It will be shipped wrapped in cushioning material and placed in a plastic bag. Thank you for looking.
