Vacuum Support (P, X)

5 points
You are immune to deleterious effects associated with vacuum and decompression (see Vacuum, p. 437). This advantage does not give you an air supply; buy Doesn’t Breathe (p. 49) for that.

Those with Vacuum Support usually have the Sealed advantage (p. 82), and often have Radiation Tolerance (p. 79) and Temperature Tolerance (p. 93), but none of these traits are required.
