The Good Pocket
Your bag holds everything you need. It just has a habit of hiding it. Lip balm at the bottom. Cables in a knot. Three pens, only one of which works.
The Good Pocket is a lightweight, washable pocket that makes the bag you already own work better. It moves from one bag to the next in one go, adapts to whatever you're carrying, and keeps the little things where you can actually find them.
