Impact suit

Impact suits were spacesuits used by an unknown species. They were extremely tough and could survive atmospheric re-entry. They could also heal any damage done.

After defeating an alien invasion in 1938 by blowing up the alien's ship, the Eleventh Doctor grabbed a impact suit after being pulled into space. He managed to put it on before crashing to Earth, though he accidentally got the helmet on backwards. Being dazed and injured from the fall, he had to be led to his TARDIS by Madge Arwell.
