I purchased this backpack a few years ago and used it several times for mountain climbing. I am selling it now because I am using a different backpack. During a climb, it got caught on a branch, and there are small holes in the right-side bottle holder and the front of the backpack. Please check the photos. After use, I wiped it down and stored it hanging in a well-ventilated place, so it is in good condition. There is no stickiness from aging. This is a used item, so please understand this before purchasing. It is a durable backpack, so it can still be used. Thank you for your consideration. Please feel free to ask if you have any questions. 【 SPEC / Product Specifications 】 ■ Brand Name: GREGORY ■ Product Name: Baltoro 75 RC ■ Product Model Number: ― ■ Color: Alaska Blue, Obsidian Black ■ Size: S, M, L ■ Material: ― ■ Weight: S / 2190g, M / 2260g, L / 2430g ■ Production Country: ― ■ Capacity: S / 70L, M / 75L, L / 80L ■ Maximum Load Capacity: 24.9kg ■ Specifications: The shoulder harness features a quick-stow system for sunglasses, allowing you to quickly and safely store and retrieve them without scratching them.
