Osprey Ariel Pro 75 Size: Women's M/L Back Length: WM/L = 40.5 - 49cm Capacity: WM/L = 75 liters Weight: WM/L = 2.28kg (actual measurement) Manufacturer's Suggested Retail Price: 68,200 yen Unused, only packed and tried on at home. I think it's the best backpack I've tried so far, but unfortunately, I made a mistake with the back length size, so I'm selling it. I packed it assuming a 2-night, 3-day solo tent stay in the snowy mountains, including rappelling gear, and it fit without any problems. A 500ml Thermos bottle fits easily in the removable hip belt pocket. The sturdy shoulder pads are comfortable and don't hurt my shoulders. There are no noticeable scratches or stains, but since I have packed it, please refrain from purchasing if you are concerned about minor details. I will reuse the packing materials. I have a cat. A lightweight backpack with excellent carrying performance and durability, ideal for transporting heavy loads and large volumes of luggage, such as long-term climbing, trekking, and guiding. The Airscape back panel, which features a comfortable and balanced carrying feel and moderate breathability, is a back system that supports heavy loads with a combination of an injection-molded frame sheet and back adjustment using webbing that easily fits the body. Equipment such as the rain cover, hip belt pockets, and side compression straps can be removed to reduce weight. The main fabric is reinforced by weaving UHMWPE (ultra-high molecular weight polyethylene) threads in a 3-thread grid, providing excellent strength and durability to withstand harsh use. It has a side zipper for easy access to the main compartment. ■ Airscape back panel for excellent balance during transport ■ Injection-molded back panel that supports heavy loads ■ Back adjustment system using webbing ■ Lightweight and durable main fabric ■ Side zipper for easy access to the main compartment ■ Removable rain cover, hip belt pockets, side compression straps, and ice tool loops ■ Flap jacket to cover when the rain cover is removed ■ Sternum strap with whistle ■ Internal hydration sleeve Women's Winter Mountains Alpine Large
