Apollo suits had a "food/drink port" but it was [apparently never used][1]. The [main purpose of the port][2] was to allow the crew to eat and drink in a contingency situation where the vehicle was depressurized and they had to survive in the suits for an extended period of time. > In case of complete loss of cabin pressure during a mission, > the crewmen might be required to wear pressurized suits continuously for as long as 115 hours. Water would be available by > passing the probe of the potable-water dispenser through the > helmet feedport. [![enter image description here][3]][3] Current US suits have an [internal drink bag][4].
