One of the signs accompanying the ICG. It reads
Each Apollo astronaut wore a two-piece inflight coverall. These coveralls
provided warmth and contained pockets on the shins and thighs to stow personal
items. This suit was constructed of a special synthetic fireproof material
known as Beta cloth.
The booties worn with this suit are also made of Beta cloth. The soles are
covered with Velcro hook material, which could attach to Velcro pile patches on
the floor of the craft to help the astronauts remain in place while weightless.
The inflight suit on display was worn by astronaut Eugene Cernan, who flew on
the Apollo 10 and Apollo 17 missions.
