The oral/nasal masks have the function to reduce the risk of CO2 breathing that could accumulate inside the helmet, isolating the respiratory system of the diver from the environment of the helmet, reduce the drowning possibility and allow the diver to breath in a possible closed circuit maintaining the possibility of communication as if he was on the surface.
The old oral/nasal masks dedicated for underwater use were made of latex, this not being a hypoallergenic material and have been prohibited and replaced by non-allergenic silicone oral/nasal masks.
Compatible with the major diving helmet on the market.
