Xercise Mask
Why don't we sell those cheap vinyl masks with no air cushion? Exactly for that reason, they are cheap and ineffective. Any leak in a mask based system destroys the simulated altitude environment. 
The Altitudetech Xercise mask is a research quality mask with adjustable air cushion and large 30mm valves for intake and exhaust. We don't skimp on materials and use medical grade silicon for our valve flappers to create a highly effective vent system that requires only the slightest of back pressures for the system to function.
Features include:
- large 30mm medical grade silicon valves
- low internal resistance
- lowest backwash of any mask
- reduced contamination of breathing lines
- adjustable cushion
