HELMET SIZING
If you feel that you have not chosen the most suitable size of helmet, Demon Tweeks will arrange free collection and re-delivery of a more suitably sized helmet (UK only).
Carefully measure
around your head,
above the ears. Take the
measurement, in inches
or centimetres, referring
to the chart for correct,
hat/helmet size. Do
not guess your size as
helmets must fit snugly
and securely before
engaging in any activity.
