"Science Fiction is speculative fiction in which the author takes as his first postulate the real world as we know it, including all established facts and natural laws."
- Robert Heinlein

E-Suit (Environmental Suit)  
  A forcefield that encloses air and heat around the body, but does not repel objects or radiation.  

In the series by Jack McDevitt starring Priscilla "Hutch" Hutchins in the 2200's, the e-suit is used for planetary exploration. We'll still be using spacesuits for a while yet.

...Hutch explained and demonstrated how the e-suits worked. "They were flexible force envelopes," she said, that molded themselves to the body, and which felt rather like a loose-fitting set of cotton clothes. The exception was the hard shell effect over the face, allowing space to breathe. ... She pointed out that the fields were no protection whatever if they fell from an embankment, walked into a sharp object, or got in the way of a laser beam.
