The Lifer helmet is available in 3 different shell sizes to accommodate different size heads. We have the Mini Lifer which is the smallest shell, the Lifer which is the middle shell size and the Mega Lifer which is the biggest shell size.
We size each one of these 3 different helmet shells up and down by thinning and thickening the sizing liners which are color coded according to size.
Our sizing liners are compatible with all 3 helmet shells.
Measure your head ...
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
Fun fact: Most kids ages 6 and under will fit into the S1 Mini Lifer Helmet. And 80% of people ages 7 and up fit into an S1 Lifer Helmet.
If you are buying a helmet for someone and you can't measure their head - follow this general rule of thumb. Ages 6 and under order an S1 Mini Lifer Helmet
