I've been keeping track of Dava Newman's work on the MIT prototype BioSuit for the past several years, and spacesuit tech just keeps getting better and better. I think future suits will also be three layers: body stocking-type skinsuit layer, smart mechanical counterpressure layer with hard seals, and a coverall-type thing with radiation shielding, pockets, and so on. Snap on some gloves, boots, and a helmet and be good to go.
