Navy BALTORO 75 backpack with adjustable straps and back padding. - Brand: GREGORY - Model Name: BALTORO 75 - Color: Navy Blue - Features: Back padding, adjustable straps Thank you for viewing. This is a Gregory Baltoro 75 purchased in 2017. I haven't used it that often, but I used it twice in the mountains for tent stays. I've also used it a few times for camping. The outer condition is good, with no fabric damage or loose drawcords. However, unfortunately, the PU material inside has deteriorated, and hydrolysis is progressing. I'm very shocked because my Gregory Triconi 60, which I've used longer than this backpack, is still in good condition, but I no longer have the energy to repair it myself, so I'm putting it up for sale. The backpack itself is a Gregory flagship, so it has a very comfortable fit and is packed with features, making it an easy-to-use backpack. I haven't used it much, so I hate to sell it, but if you understand the internal deterioration, please consider purchasing it. If you don't mind your gear getting a little dirty, it's still a backpack that can be used without any problems, and honestly, it's a backpack with such a high level of completion that it's a shame to let it go. Includes rain cover and bottle carrier/attack pack. The rain cover has never been used. * By the way, I looked it up online, and it seems that you can remove the coating from a backpack that has undergone hydrolysis by soaking it overnight in hot water with baking soda and scrubbing it with a brush. However, it seems that the waterproofness will definitely decrease. Also, you can remove the peeling coating material from your luggage by shaking it off. It doesn't stick that much, so you can remove the coating agent that has fallen inside the pack with a vacuum cleaner.
