This Mark Ryden Huge Laptop Backpack (£33) is almost as big as a carry-on suitcase, and easily holds enough for a few days away, making it perfect for those who're tired of wheeling along a tiny suitcase every time they go on a short trip. It has two compartments; one of which has a padded laptop sleeve (the "digital zone"). The whole thing has multiple pockets throughout to keep you organised, including an anti-theft pocket for valuables that sits against your back. There's even space for a power bank that leads to an external USB socket, so you can charge your devices straight from your bag.
