Buffs come in hundreds of different designs from the plain to the bizarre; we've got our eye on a Chupa Chups one next. You'll doubtless have seen the original Buff (£10.99) - a simple polyester tube that you wear as a scarf, under-helmet hat or balaclava. But there are loads of more elaborate versions too.
The Reflective Buff (£11.99) features Scotchlite stripes, while the Cyclone (£24.99) has a Windstopper fleece section to stop cold air getting down your neck. The Typhoon (£24.99) is even warmer, made from Polartec fleece with a Windstopper upper and drawstring.
