Size and security
An essential element of the safety of the mask use is that it must fits perfectly to the contour of the user's face.
The design of the injection solution has been made after an ergonomic study that gives us a solution to most users, a size L that wants to be as universal as possible. But not everyone can wear this mask, you also need a small size, an extra large size, and in some cases a personalization is an added value in comfort and safety.
For maximum security, a set of 3D models is available. These masks allow personalized help to the outline of the user's face.
At the moment, these 3D models make it possible to supply masks of different sizes, waiting for the injection molds of the other sizes to be made.
