Measuring your head for a helmet is important to make sure you get the right fit. We 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 eyebrows, 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 eyebrows.

Once you get your measurement compare it to the sizing charts on the individual Lifer Helmet product pages to see which Lifer will fit you.

• If it measures 18" - 20.25" get an S1 Mini Lifer Helmet
• If it measures 20.5"- 23.25" get an S1 Lifer Helmet
• If it measures 23" - 25.5" get an S1 Mega Lifer Helmet

It is very important that your S1 Lifer helmet is worn correctly and fitted properly. Your Lifer Helmet should be worn so that it is level on the head and sitting at the middle of your forehead. It is very important to always clip the strap on your helmet and to have your strap adjusted to the correct length, allowing for a minimum of two fingers to be placed between your strap and your chin.

You tighten the strap by pulling the excess strap through the helmet clip until you find the ideal length. The excess strap should be folded up and secured using the rubber O-Ring.

The strap sliders should be adjusted so that they rest just below the ear lobes. A properly worn helmet should not be tipped back on your head, worn backwards or worn too low on your forehead. A properly fitted helmet should be snug but not so tight that it gives you a headache. There should be no side to side or front to back movement on your head.

Once you get your Lifer Helmet sized and adjusted properly you are ready to roll!
