We used one of these all through the winter last year, and now the clocks have changed (you didn't forget did you) we've dug our Hump out of the wardrobe. For safe commuting they're an essential purchase, they may not look stylish, but safety is paramount.

The Hump is a reflective backpack cover, covered with 3M reflective material and also doubles as a useful way of keeping your backpack dry if you ride sans-mudguards. Elasticated edges mean it fits most backpack designs, and two stretchy bands secure it in place.

New for ths winter is the Hump P15 which has a battery powered light system. Two long sections of piping the length of the cover add additional visibility, plus a new flourescent bum panel. Two AA batteries are concealed in a waterproofed container, and the light can be set to constant or flashing.

Prices range from £14.99 to £39.99. More information at www.respro.com
