All KASK helmets purchased come with an inner lining included.
Liners sizes - every cm from 50 to 63cm. Helmets are sold in the size range of liners that fit in that shell. Please specify the liner size you require at check out.
For example for a 58cm helmet select 57-59cm and specify 58cm liner at check out.
The size of the KASK helmets corresponds to the circumference of your head! You can use a tape measure positioning it just above the ears, and taking note of the measurement in centimetres.
