Sizing Your Helmet

General Sizing

Measure:
See below for further instructions on measuring for a specific model of a Trauma Void helmet.

Fitting:

Place the helmet level on the rider.  If the helmet contains a dial, adjust the dial to fit the rider securely.  Without harnessing the chinstrap, have the rider shake their head from side-to-side and again from front-to-back, check for movement and ask the rider if there is an even pressure or if there is any pinching or air pockets.  If the helmet does not have a dial-fit system and there is movement from side to side but not front to back, try our oval liner, which is thicker on the sides than front to back.  If there is movement overall or front to back, try going down a size. Once you’ve found a secure fit, move the brim of the helmet up and down, the rider’s eyebrows should wiggle. 

Adjust the Chinstrap: 
The length of your chinstrap should rest just under your chin and touch the bottom of your ear lobe. You should be able to fit one finger in the space between strap and your chin. The strap should be secure, but still allow you to move your head up and down comfortably.

Helmet Fitting/Measuring: 

To measure for the best fit, find the circumference of the head.  To begin, use a flexible tape measure and place it 1-1/2 cm above the eyebrows, skimming the tops of the ears, take it around the back of the head to the fullest part.  To find your size, round up to the nearest centimeter and go up one size from that measurement. Please note that the rider’s hair should be as worn when using the helmet.
