<p>A hockey helmet includes earpieces that are readily removable from the helmet without the need for tools or other objects, and without the need to remove screws or other components. The earpieces may be slidably attached to rails on a retention mechanism embedded in the foam helmet liner or to rails on the helmet shell itself. The helmet optionally includes an internal region of EPP foam fused or bonded between two thin polycarbonate layers, with the retention mechanism embedded within the EPP foam.</p>
