Felix Baumgartner, who jumped from the upper stratosphere in the Red Bull Stratos project, wore a pressurized suit in which he could obviously do better than Apollo's astronauts in their A7L and A7LB moonsuits. It is suited for 1g gravity (and should therefore be even more comfortable in 0.38g and 0.166g).
Could Baumgartner's suit respectively a modified version of it be used for lunar and Martian expeditions? Are there any disadvantages? A similar question may apply to Eustace's spacesuit but Eustace just let himself hang on his balloon so I can't tell how comfortable the suit was for him.
