Technology details
IsoFit® headgear: a step change in ergonomics and working comfort
The IsoFit® headgear is an advanced three-dimensional support system that replaces traditional rigid designs. Its key element is a unique cable system that wraps around the head and, with a single knob, adapts precisely to its individual shape. Combined with multi-plane vertical and horizontal adjustment, it lets you set the centre of gravity of the helmet precisely. The weight is spread evenly over a large area instead of a few points, which greatly reduces the feeling of pressure. The system keeps the helmet very stable in every working position, so you do not have to keep readjusting it. IsoFit® headgear is a direct investment in your own health and reduces the risk of chronic neck pain.
