Abstract
A watertight suit is capable of properly discharging air within the suit and safely maintaining a diver's position in the water. The suit includes an air outlet valve provided in an end section of a leg part, the air outlet valve functioning to discharge air from the inside of the leg part. Another air outlet valve can also be provided in an upper body part of the suit. An air inlet introduces air into the watertight suit as necessary to equalize external pressure. Where an automatic air outlet valve is provided, air in excess of external pressure is vented through the outlet valves automatically as warranted by the diving conditions, keeping an even balance of pressure even when air is excessively supplied form the air source through the inlet valve.
