It’s a mere 4 ounces but will hold up to 16L of stuff! Don’t be fooled by it’s tiny size, the Nobo Packable Backpack from our friends at earth pack has many of the features that you’d find in a standard backpack. A large stretch mesh side pocket is big enough to hold our big 32 ounce reusable water bottle. A bungee cord system in the front of the bag makes it easy to carry a sweatshirt or windbreaker when you’re ready to peel the layers off. An interior pocket holds smaller items that you want to keep separate from the main compartment, and a built-in zippered, top pocket stores items that you need quick access to like sunglasses, keys, or your phone. That top pocket is also the pocket that allows you to fold up the pack into itself for a compact 7.5 inch by 4 inch thin bundle with a small carry handle.The lightweight ripstop nylon is durable, and the air-mesh backpack straps are surprisingly comfortable, even when the pack is fully loaded. The earth pak Nobo Packable Backpack is such a convenient carry option to stash in your car, your purse, or your luggage for those little extras that you pick up on your travels!
