This is the offshore version of the ST4 GT W Fiberglass helmet. It is made from a Kevlar Multi-Sandwich Fiber composite formed in an autoclave. It carries the same Snell 2010 certification as the Carbon helmet, but the different material adds the weight. This different material yields a slightly heavier helmet, but at a reduced cost. The Snell 2010 rating satisfies almost all racing sanctioning bodies’ requirements for helmet certifications.
The ST4 GT W is designed to satisfy those closed cockpit drivers who yearn for a larger eyeport. The cutout for the eyeport is taller than the standard Formula version and has a special visor to accommodate the larger opening.
The Offshore version comes standard with Noise Attenuating Earmuffs with integrated speakers, and a Magnetic Dynamic Microphone. Optional Air Supply and Hydration are also available. There are no wires or hoses hanging down below the helmet - everything integrates seamlessly with the shell of the helmet. Features an M6 nut integrated into the shell to interface with Head and Neck Restraint Systems.
