Regardless of the explanation, it was a padded rubber muscle suit. Even more meaningless as Shipp was in great super-hero shape!

So I guess you don't remember the episode then. Because after the explanation Barry said something to the effect of "I feel it molding to me and expanding" to which Tina explained that it's the way the suit does the heating and cooling. If you have the DVD it's the scene in the pilot at the running track before they try to test his top speed.
