How to deal with a helmet that rides up your forehead

Many people just buy a helmet off the shelf put it on their head feel that it is a good fit then buy it. A poor fitting helmet is not comfortable nor is it safe.
the correct way to buy a good fitting helmet takes a little more than this.
firstly select the helmet that you like.
second find the size that fits nice secure it then do these simple tests.
reach over your head grasp the helmet by the top just above the eyeline then pull the helmet up, if the helmet lifts then it is the wrong size or type, reselect find the helmet that will not pull up or only pulls up a tinny bit. As at high speed it will feel like it is trying to pull your head off.
now grab the helmet by either the jaw line (in the case of a full face helmet) or with both hands around where your ears are try to twist the helmet from side to side you want very limited movement here too. Hope this helps.
ALL HELMETS ARE NOT CREATED EQUAL. stay upright folks.
