It's hard to believe that there are still riders out there who have yet to be convinced of the benefits of a back protector. Essential on track days and – if you think about it – just as essential every time you ride, the Knox Aegis is claimed to be "the most technically advanced back protector available."

According to info from Knox, "statistics show that over 25 per cent of injuries to motorcyclists rated 'maximum' or 'critical' (the ones that cause crippling injuries or death) affect the spine yet there are still a significant proportion of riders unwilling to use a back protector. So the design team at Knox concentrated on tackling comfort, safety and style to resolve the issues raised by riders as significant factors when choosing a back protector. By developing solutions to these issues Knox have produced the most technically advanced and user-friendly back protector available today."

And, to help you find an Aegis that fits, Knox is offering the Aegis in no fewer than seven different sizes engineered specifically for children, women and men.

It has a multi position waist strap system that may be adjusted not only for length but also moved up and down, giving precision fitting. It also ensures that the rider can fix the back protector in the correct position so it does not ride up during use. All sizes have a new integral shoulder strap slider system too that allows the straps to adjust automatically.

It should cost around £79, depending on size. You've only got one spinal column, so wear a back protector that fits. www.planet-knox.com
