Stafford's Apollo 10 Inflight Coverall Garment (ICG)

The museum uses one of the most unusual method of displaying an Apollo inflight coverall garment: Showing Tom Stafford wearing it, floating in space.

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.
