Multifunctional black nylon backpack. - Color: Black - Style: Backpack, Business Bag, Briefcase - Material: Nylon - Storage Pockets: Multiple pockets - Country of Manufacture: United States of America Purchased about 4 years ago from a select shop for around 40,000 yen. While there's no exact official capacity, I'd estimate it to be around 25 liters. The two front pockets can also hold a considerable amount of items. The bag itself is very lightweight, and its durability as a made-in-USA product was a key factor in my purchase. I used it daily for commuting and for trips of around two nights without any issues, so I think it's very user-friendly. Inside, there's a large mesh pocket where I kept valuables. There's also a divider that can be used for storing a laptop. In my case, I stored my company PC (Let's Note) without a cover. A small orange pouch is also included inside. I'm selling this because I recently bought a new backpack and would like someone who will use this one a lot to have it. Thank you for looking.
