This Altitude Mask allows you to breathe 100% naturally and can be used during most training and workout programs. It creates the effect of high altitude by restricting the amount of oxygen that can come through the mask. This forces your lungs to work harder and your cardio and stamina to gradually improve. You can taper the amount of air you would like the mask to restrict and it comes as a one size fits all.
Masks are shipped separately from the rest of your order, so there is an additional shipping charge.
