Avoid rider and pillion helmets coming together with an uncomfortable thwack by using the innovative new Oxford Bumper helmet protector. These knocks are almost unavoidable when riding pillion, but if you attach a Bumper to the back of the rider's helmet, you can minimize the damage and discomfort. This unique product uses a carefully formulated blend of special materials to be extremely grippy without using adhesives. This means that you can take it on and off any number of times, either for repositioning purposes or because you only want to use it when riding with a pillion. Choose from one of seven quality designs to protect your helmets and look good in the process.
