Helmet is B.S.I. approved to P.A.S. 028:2002 Marine Safety Helmet standard and C.E. marked. Inflatable Liner - This is an integral part of the helmet design. Through an oral valve, the liner has the ability to inflate or deflate accommodating the user's head size. This system allows the 'tension of the fit' to be adjusted according to the situation, resulting in increased comfort, additional buoyancy and improved heat retention.

It is removable for washing and secured in place using a Hook and Loop system. Replacement pads are available. Ear Defense System - The Black Nylon blanking unit is fitted inside of the rubber grommet. When in place it provides ear protection from external noise such as engine, wind or inclement weather. It can be removed for improved acoustic clarity. Alternative vented option also available. Strap Assembly - This retention system consists of 19mm nylon webbing riveted to the shell at two point fixings. The Patented Fastex 'click' closure buckle allows one hand release and quick adjustment to the strap length. Offset side buckle aids access in emergency and prevents contact with windpipe. Looped end aids tensioning and neoprene sheathed comfort tube helps prevent rubbing. Top Head Piece - The Foam Headliner provides shock absorbtion from impact in the crown area and additional floatation from its foam construction.
