This is the EXPED Metro. It's the larger 30L model, color is dark gray black melange. I used it for commuting 2-3 times a week for about six months. I don't smoke. I liked it because it was easy to carry, but I'm selling it because I'm replacing my commuting bag. Since it's 30L, I could use it for business trips of 1-2 nights. The bottom is still clean because I don't put it on the floor. I think I bought it for around 25,000 yen. The size is 56 x 29 x 19 cm. Below is the official product description. The Metro, with its clean design, is a comfortable and versatile pack for use in the city. The thermoformed back panel, ergonomically shaped shoulder straps, and removable hip strap make the Metro very comfortable to carry. The inner lining fabric is recycled and has a water resistance of 3000mm for enhanced protection. There is a padded PC storage space that can be accessed with a zipper without opening the main opening. There are pockets on both sides for umbrellas and water bottles. The zippered slot pocket on the outside can store valuables and has a carabiner lead for keys. Two internal mesh pouches on both sides of the base and an envelope pocket inside the frame allow you to organize and store your luggage even in the main compartment. ・Minimalist and functional backpack made for urban outdoor use ・Durable ripstop polyester, bluesign certified ・Roll-top closure for quick access to the main compartment ・Laptop compartment that can store up to 15 inches for quick access ・Thermoformed back panel ・Two side pockets and one front pocket for easy organization ・Tail light can be attached for convenience when riding a bicycle at night
