The MK2 head strap provides extra stability for your mask. The strap attaches to the valve fasteners and is secured by the valves. When worn, it fits over the top of the head. It reduces the pressure on the nose region and provides a more stable fit. This new upgrade version has an adjustable facility on the elastic that stretches over the top of the head.
The head strap is an added feature for our masks which some people may prefer but, it is not essential for the effective function of the mask.
It comes in one size (adjustable) and can be used with or without a Proseal®.
