An interesting mask is revealed by Valken Tactical at the SHOT Show 2018, the Valken Switch Mask. This has a removeable flip-up face guard with dual pane thermal lens. It also has a removeable top and bottom ventilation. You can fli-up the lower part if you want more ventilation to your face and lower it after to keep you protected or you can remove it and just use the goggles to protect your eyes to keep you more comfortable.
