Evoke liners are washable, padded, breathable liners that provide the correct fit for rider's head. All evoke helmets must be used with an evoke liner for the helmet.
Fit: Standard vs. Custom Liners
Callisto has three shell sizes: Small, Medium, and Large.
Small: fits 53cm – 55cm heads
Medium: fits 56cm – 58cm heads
Large: fits 59cm – 60cm heads
In cases where your head falls between shell sizes, the custom liners will help achieve the best fit. For example, if your head measures 58cm, but is on the top end and possibly a little too snug, you may need to go up to 59cm. Because you are moving up to a large shell, you may need some extra padding to take up the extra room. The custom liner for 59cm offers 12mm or 15mm of additional padding.
