Chrome Industries 22x Yalta 3.0 ($180)

For those looking for something even bigger and more durable, Chrome Industries’ 22X Yalta 3.0 backpack is designed to handle pretty much any situation. The bag’s laminated Cordura fabric helps keep the weather out, while its rolltop back makes sure no water is getting inside (unless you want it to). The official description says the padded laptop sleeve can handle laptops of up to 15 inches, but I’ve actually managed to fit some new thin, light, 16- and 17-inch notebooks in there too. The lifetime guarantee means you can send pictures of issues in to the team at Chrome and get a new one.
