This is the Gregory Covert Overnight Mission. It's a convenient 3-way bag that can be used as a backpack, shoulder bag, or carried by hand. I mainly used this for domestic train travel because it's easier to move around with than a carry-on suitcase. It was suitable for business trips of about 3 nights. There is some wear and tear, but there are no scuffs on the corners, and I think it can still be used for a long time. I bought it about 5 or 6 years ago for around 30,000 yen and used it about once a month. I don't smoke. The original gadget case is included. As a bonus, I'll include a 13-inch PC case that I bought for business trips. Actual measurements are as follows: * Height: 34cm * Width: 45cm * Depth: 17cm * Shoulder strap length: 67cm - 122cm Material: 630D Cordura nylon Color: Black Accessories: * Shoulder strap * Logo gadget case
