This is the Montbell Angler Pack 15. I tried it on indoors 2-3 times, but it has never been used. I think there are no noticeable scratches, stains, or signs of use. [Item Number]: 1126178 [Material]: Front, Bottom: 100-denier Ballistic® nylon triple ripstop [urethane coating] Shoulder Harness: Monofilament mesh, 3D mesh Back: 3D mesh [Weight] 464g [Color] Dark Gray (GM) [Size] Main Body: Height 48 x Width 32 x Depth 16cm / Chest Pocket: Height 18 x Width 13 x Depth 4cm [Capacity] 15L This is a lightweight fishing backpack with a high-waist design, incorporating the know-how developed in the development of mountaineering backpacks, and equipped with a variety of pockets for efficient storage of necessary tools. The main body uses a fabric that combines lightness and durability, and the back panel and shoulder harness use 3D mesh that is breathable and prevents stuffiness. It offers excellent fit, reduces load sway, and is ideal for a fishing style that allows you to move lightly while exploring points.
