Thank you for viewing. This is the AMG 75 BACKPACK (AMG 75 Backpack). I purchased it last year and used it once for a 4-day long trail. After use, I removed and washed the shoulder and hip straps, and wiped the rest with water before storing it. I used a backpack cover, so there is almost no sign of use or dirt, but please understand that this is a used item before purchasing. Even when the weight became quite heavy, the straps are very sturdy, making it an easy-to-carry backpack, and I liked it, but I am selling it because I don't use it often. With various attachments, it's perfect not only for long treks and long trails, but also for winter alpine climbing and backcountry! Also, it has a unique design and color, which is rare for a mountaineering backpack, and it's very cool! The following is a product description. Features: A large backpack that covers from long summer treks to winter alpine climbing. The side parts use a 200D ripstop material that blends Spectra, a high-strength material with 12 times the durability of iron by weight, and nylon. This is a new standard alpine pack that is particular about comfort and compartments. Specifications: ・The bottom is 840D nylon with carbonate coating. ・Front panel is X-PAC DX40 ・Height-adjustable shoulder harness and waist harness ・Removable rain cover (two pockets on the outside, one on the inside) ・Avalanche gear compartment ・Crampon pocket ・Stabilizes loads of all sizes ・Large front zip pocket (for storing avalanche gear, etc.) can be used even when the main compartment is fully loaded ・Tool carry system Recommended for those looking for mountaineering backpacks such as Gregory, north face, Osprey, HYPERLITE MOUNTAIN GEAR, Millet, Arcteryx, and UL backpacks!
