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.

SizeHead circumferenceNotes
XS51–52cm20.5" nominal
S52–53.5cm21" nominal
M53.5–54.5cm21.5" nominal
L54.5–56cm22" nominal
XL56–57cm22.5" nominal
XXL57–58.5cm23" nominal
XXXL58.5–60cm23.5" nominal

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 around the widest part of your head, about 2.5cm above your eyebrows and just above your ears. Keep it level and snug but not tight, and read the number in centimetres.

No tape measure? Use a piece of string or a shoelace, mark where it meets, then measure the string against a ruler.

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.
