Ashton Eaton is a world record holding olympic decathlon runner, and Nike like standing behind athletes of his caliber. In doing so they are working on creating a pieces of headgear called an "Ice Hat" which will keep Eaton's head cool between events.

Nike decided to 3D scan his head and then print a replica in order to develop a 1:1 replica for building the perfectly fitting hat around.
