The SCL has two features that make it a very comfortable liner; the visco-elastic foam in the cover and the thermoplastic layers of the liner. The visco-elastic foam’s temperature softening properties allow the cover to conform to individual shapes when in contact with a warm surface, distributing weight evenly while reducing pressure points and "hot spots." on your head. The thermoplastic layers above the cover are molded to create dimples, which partially collapse to conform to your head due to the heat from your head. These layers also contribute to the impact protection of the helmet.

The SCL is lined with a removable and washable liner that is attached with hook-and-pile fastening tape to an Energy Absorbing (EA) liner.
