I purchased this at IBS Ishii Sports in Umeda, Osaka, about 50 years ago. I used it for Boy Scouts, about 10 days a year for about 6 years. After that, I used it once every few years, but I always dried and stored it properly. For the last 20 years, it has been stored in a closet. There is some soiling due to age, but the material itself doesn't seem to have deteriorated, and it still functions well as equipment. I've forgotten the model name, but I think it had a capacity of about 60L to 65L. It also has side pockets that can be stored away. At the time, when the kissling backpack was the mainstream, this was a cutting-edge item, and overseas brands like Jansport and Kelty were considered as competitors. I think IBS had a pretty wide variety of original backpacks. I think this type of backpack is very rare, so I would like to sell it to anyone who is looking for one. I think it would look pretty cool to use it casually now. Please understand that this is a vintage item and no claims or returns will be accepted. #️⃣Ishii Sports #️⃣Backpack
