High performance ventilatory training mask incorporating multiple and adjustable air admittance valves for replicating various encountered altitude resistances
A wearable training mask providing varied inhalation resistance settings and including a depth defining and air impermeable body having an exterior surface and an interior surface exhibiting a perimeter extending seal such that the body is adapted to overlay a wearers mouth and nose. A plurality of air admittance valve subassemblies are provided and incorporated into locations along the body. Each of the valve subassemblies exhibit multiple resistance settings for affecting a degree of air flow into the mask in response to inhalation by the wearer.
