Tumi's latest special edition backpack is something rather different from the usual offering for laptop-toting.
The limited Edition PowerPack was designed by Anish Kapoor and integrates a small solar panel that generates enough electricity to recharge a mobile phone or PDA, and, we assume, a portable media player.
If that wasn't enough goodness for one bag, 100% of the profits from the Powerpack go straight the Medecins Sans Frontieres/Doctors Without Borders. They don't come cheap – to buy one of the 500 that are being made, you'll have to fork over $695 (£375).
Inside the pack there's also a Tumi Electric Adaptor, a removable laptop sleeve, a flashlight key fob, removable accessories compartments, and pockets for various pieces of kit, including camera and water bottle. Inspired by the needs of humanitarian workers around the world, the pack is also water repellent and made of ballistic nylon.
Go on, you know you want one.
