Do you ride a bike a lot? Is your helmet as comfortable as you would like it to be? If not, why not try a neck cushion, which inflates when you are close to danger.
They have recently been invented in Sweden as a cycling helmet substitute. They have been in development for over 6 years.
They are much safer than average helmets and, because they are worn on your neck, stop you getting helmet hair!
Although it is thought the cost will go down, the current price is £370 per helmet, but still a good investment for cyclists.
