This is an Osprey Farpoint 40-liter backpack. Please note that it shows some signs of use. I'm selling it because I haven't been using it lately. I used it for city use, and never for outdoor activities like mountains. You can stow the straps and use it as a handheld bag. It's perfect for 1-2 night business trips. You can separate the compartment for clothes and the area for a laptop, etc. The mesh pocket on the back can hold fairly large items like water bottles. The laptop sleeve is durable. It fits a 15-inch Macbook. From the following website: Live Adventure. The Osprey Farpoint 40 backpack is the lightest travel backpack.
