Here’s a Timbuk2 Impulse bag bought from the brand itself. It’s 55 liters, and the hip and sternum straps are included. It’s been used but has recently been in smoke-free storage since I’m not traveling as much. It has a bit of exterior wear, and the inside is in excellent shape with all functioning zippers and has no stains. The bag is awesome and feels indestructible, and it has a lot of life left. It’s similar to travel bags and backpacks by Cotopaxi, Patagonia, and Osprey. Let me know if you have any questions. Thanks!
