Features:

With this mask, high-altitude training can be simulated in the plains. At high altitudes,
the air is thin and has low oxygen levels. Blood can not absorb oxygen normally as usual,
and the heart rate increases. Training in this ring, can enhance lung capacity, diaphragm,
heart load intensity, anaerobic threshold. So when you go back to low altitude, your performance
or training will improve, so most people will go to high altitude for training.

Lean people choose S, partial fat people choose L, most people choose M, this is flexible,
do not need too tangled models, each size difference of 1cm.

The role of the mask is to limit the volume of oxygen by limiting the volume of air entering the mask.
The player, the player, can enhance the training intensity by wearing the mask and enhance the overall strength of the player.

One for the exhalation port (can not be closed), two air intake (can be closed)

The mask simulates elevation from 3000 feet to 18000 feet.

You can adjust the altitude by changing the cover of the air intake nozzle.
