Comfort was a key aspect of the ATLAS 4.0 design process and our brand-new tailor-made cheek pads and headliner offer you the comfiest riding experience in an ATLAS to date. Our multi-layered foam of different densities and soft moisture-wicking outer fabric provides you with a comfortable and secure fit. The new ATLAS 4.0 Core is the quietest Core yet due to the removal of two of the top vents and sound dampening ear inserts which can be placed in the helmet to further reduce sound around the ears. We took climate control a step further with our two front vents which can be adjusted to a total of 4 pistons for greater temperature control inside your helmet.
