Measuring your head for a helmet is important to make sure you get the right fit. S1 designed the Lifer Helmet with safety in mind, and getting the fit right is critical. It is easiest to do this with a soft measuring tape but if you do not have one you can use a string or a cell phone charging cable and then measure that against a ruler or hard measuring tape. You need to measure your heads circumference and will want to wrap the measuring tape starting in the middle of your forehead and just above your eye brows, then around your head above your ears and back around your head to the middle of your forehead where you started. Put simply you want to measure your head where your hat would normally sit or where you would imagine the helmet to fit on your head just above your eye brows.
