Bag Lust: The Ghostbusters Proton Pack

It might not be elegant, professional or sophisticated. But even if you only use it to keep your gym kit in, this Ghostbusters rucksack is geekily kitsch and cool, and ideal for fighting any rogue supernatural spooks, ghosts and ghouls.

Based on the design for the original proton packs used in the classic 1984 film, the back panel is padded to keep you comfy even when you're carting all sorts of bits and bobs around. It's £40, from Truffle Shuffle. All together now: "Who you gonna call? GHOSTBUSTERS!"
