The ATLAS 3.0 Thicker Headliner is used to make the fitment of your ATLAS 3.0 helmet slightly tighter without completely downsizing.
Please select the size of your ATLAS 3.0 helmet - for example, if your helmet is a medium select size medium thicker cheek pad. You can find the standard headliner here if you are just looking for a replacement headliner for your helmet.
