The Super Plasma PL climbing helmet is well ventilated. Polygiene® treated inner padding for antibacterial hygiene can be easily exchanged. The helmet comes with external lamp carrying clips, a new Up-N-Down size adjustment system with a central ratchet wheel and two lateral finger push winglets for an ultimate fit. A plastic adapter for plug-in helmet-mount ear defenders is available. ATTENTION: Peltor visors do not fit with the new adapter. Mounting screw ear protectors is not possible anymore.
