It doesn't have to be particularly heat proof.

Most of the heat that's generated during atmospheric re-entry is as a result of the angle of re-entry and the sheer speed that the craft is travelling at. In this instance, he was jumping from a (relatively) static platform, i.e. straight down. Atmospheric re-entry from a space vehicle is always at an angle that means that they actually have to pass through an awful lot more atmosphere at a higher speed (due to orbit).

It does provoke a question though. Is atmospheric re-entry from low-Earth orbit without a vehicle technically possible? Certainly in many respects it is but heat shielding is the big issue.
