S-One Lifer sizing

S-One sizes the Lifer by nominal head size in inches. Each helmet ships with three liner thicknesses, so every size has about an inch of adjustment built in.

Same shell for the Lifer, Retro Lifer, Retro Lifer E-Helmet and Lifer Visor. Between sizes? S-One says go larger and use the thinner liner. Under 51cm look at the Mini Lifer; over 60cm the Mega Lifer.

How to measure

Wrap a soft tape measure to measure the circumference (around) your head an inch (2.54cm) above your eyebrows. Keep the tape level front to back around the widest part of your head. Keep it level and snug but not tight. If you don't have a measuring tape, use a piece of string, shoelace, spaghetti* or snake** then lay it out on a table and measure it with a ruler.

*Make sure the spaghetti is cooked or the snake is asleep.

**LUXBMX does not recommend using a snake to measure the circumference of your head. (It's a joke)

Between two sizes? Most helmet brands recommend the larger size and using the thicker set of pads. A helmet should feel snug all round with no pressure points, and shouldn't rock when you shake your head.
