A breathing equipment for high altitude flights comprises a breathing mask provided with a breathing gas regulator capable of supplying breathing gas under pressure and a helmet. The helmet is provided with means which, if the pressure of the breathing gas supplied to the mask is higher than the ambient pressure by an amount exceeding a predetermined threshold, subject those organs of the head which are particularly sensitive to the pressure differential to a gas over-pressure sufficient to avoid physiological troubles.
