Evoke Helmet Liner for Callisto Helmets

Evoke liners are washable (hand washing recommended), breathable liners designed for Callisto models to provide the correct fit for rider's head. Evoke Liners have a padded nape.

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 – 61cm heads

In cases where your head falls between shell sizes, the custom liners will help achieve the best fit. For example, if you normally wear 58cm, but it feels a little too snug, you may need to go up to 59cm, which goes from medium to large shell. Because you are moving up to a large shell, you may need some extra padding to take up the extra room, choosing the 59cm with either 15mm or 12mm of padding. 

The liners are listed from smallest to largest. Because the millimeters refers to the amount of padding in the liner, more padding makes the liner fit a smaller head. Thus the higher numbers appear first in the list. In cases where there are custom sizes, the millimeters for the standard in that size is provided for comparison. 

All evoke helmets must be worn with the evoke liner designed for that helmet. Helmets should never be used without a liner and liners are not interchangeable across models. Callisto models use Evoke Liners; Elara models use Elara Liners; Orion skulls use Orion Liners.
