I purchased this for my child's school trip to climb Mt. Fuji. I believe it's in like-new condition, having been used only once. I will also include a separately sold 3L water pack, which is unused but has been rinsed. As shown in image 3, there is a small name written on the inside of the bag. The blacked-out area in the photo is for privacy; the actual bag has the name written on it. Weight: 971g Capacity: 30 L (Height 56 x Width 29 x Depth 17 cm) Back Length: 53 cm Built-in Rain Cover Features: Chest Support / Hook Code / Trekking Pole Pocket / Hip Belt Pocket / Belt Holder / Rain Cover Like the name "Rei" (meaning "wind" in the Ainu language, a native tribe of Japan), this backpack uses the VBR system on the back panel for excellent breathability. Breathable mesh material is used for the shoulder harness and waist belt. VBP: Ventilation Backpack Panel System: A system that improves breathability by floating the back panel with a metal frame, creating space between the body and the waist. - Brand: mont-bell - Color: Olive Green - Capacity: Approximately 30L - Hydration System: 3.0L Hydration Pack (sold separately) - Features: Adjustable shoulder straps - Number of Pockets: Multiple zippered pockets Thank you for looking.
