Size Chart:

Below is a general guide based on body weight (note that facial measurements are more accurate for ensuring correct fit). This size chart is indicative:

• S: 45 - 65 kilograms
• M: 65 - 100 kilograms
• L: + 100 kilograms

How to use:

There are two valves inside the mask. One of them has a green silicone valve inside (see images). And the other one is empty. This valve opens and closes under pressure.

To begin, we recommend leaving it like this, until we get used to training with the mask. We can regulate the air flow with the side levers. The number 1 is the softest (more air enters) and the number 4 the hardest (less air enters). We can leave one side in the 1 (the softest), and go up the other, and little by little get to have both sides in 4 (the hardest).

Once accustomed, we can add one of the transparent valves that comes in the bag inside the box (the other is spare). In the valves that are inside the mask, we open the one that is empty and add the transparent silicone valve that comes in the bag. We must put it backwards of how the green valve is, as a rule, with the flat part down. This is the hardest way, with the silicone valves on (the green that is already on and the transparent one).

The front cover does NOT need to be removed.
