Aldrin's Apollo 11 Inflight Coverall Garment

The space suit display includes a Buzz Aldrin inflight coverall garment (ICG). There's no indication as to whether this was actually worn or flown, or whether it was merely a backup or training garment.

The ICG was a three-piece flight suit consisting of a jacket, trousers, and pair of boots. It was designed to be worn over the constant wear garment whenever the astronauts were not wearing space suits, and most in-flight photos of astronauts are of them wearing the coverall. The boots had Velcro patches on the soles for restraint.

The ICG kept the constant wear garment clean, provided additional warmth, and provided stowage for miscellaneous personal equipment in a shirtsleeve environment. The ICG had a passthrough for bioinstrumentation.

The ICG was originally constructed of Beta cloth but quickly changed to Teflon-coated Beta cloth for durability. This fabric irritated the crewmen's skin, so the jackets were lined with Nomex. That didn't solve the problem, so the material was finally changed to a woven Teflon fabric.
