Helmet Size Guide

To find your correct helmet size, measure your head circumference just above your eyebrows using a soft measuring tape. The measurement you get corresponds to your helmet size listed in centimeters (cm).

Helmet Shell Sizes – Samshield 2.0 Helmets

Shell Size Available Measurements (cm)
Small (S) 52, 53, 54, 55 (S), 56 (S)
Medium (M) 55, 56, 57, 58 (M)
Large (L) 57 (L), 58, 59, 60, 61
Extra Large (XL) 61 (XL), 62, 63, 64

Note: Some sizes are available in two shell sizes (e.g., 55 cm fits both S and M shells). Choose the shell that offers the best comfort and fit. If you’re between two sizes, we recommend going with the larger one.


Helmet Liners

When you buy a helmet, you get a liner for free — just make sure to add your preferred liner to the cart manually when purchasing your helmet.

All Samshield liners are removable, washable, and designed to provide a tailored fit for enhanced comfort and hygiene.
