2. The Apollo Moon Suit

The Extravehicular Mobility Units worn by Apollo astronauts while walking on the Moon are without parallel. The oversized helmet and mirrored face shield are as iconic as it gets. The Portable Life Support System, or backpack, finishes the classic look. Sure, Apollo astronauts had difficulty walking and moving in these outfits, but the Moon suit got the job done, allowing Neil Armstrong to make that giant leap for mankind.
