I have a question for the experts. I understand that the A7L suit in the intravehicular configuration had black rubber gloves. During moon walks, the gloves consisted of these same black rubber pressure bladders with a covering over them (Chromel R with silicone fingertips). My question is, was one pair of pressure bladders issued to the CDR and LMP and a separate Chromel R glove cover slipped over them during EVA, or were two separate glove assemblies (so two pairs of pressure bladders) issued, one for IV and one EVA? |

I am pretty sure there were separate complete EVA gloves aboard as well as the IVA gloves which they wore during launch. |

The Smithsonian's description of the EV gloves supports Rick's understanding: The EV glove assembly is a modified Intra-Vehicular (IV) glove covered with a multi-layered assembly providing scuff, abrasion, fire and thermal protection to the interior. Woven stainless steel (Chromel-R) is incorporated over the palm for additional thermal insulation, and the fingertips are made of high strength silicone rubber which provided a measure of sensitivity for the astronaut.EV gloves were designed to be locked into place with a "dog" and "O" ring system, and the IV and EV gloves were interchangeable. The wrist locking rings were color coded with blue for the left wrist and red for the right. Each EV crew member also had back up EV gloves aboard the lunar module. |

Thank you. I just got confirmation from Ulli Lotzmann that there were two different assemblies issued. Only Cernan and Schmitt had spare EVA gloves though, according to him. |

I think it was the movie for All Mankind that the "LOL" (Little Old Ladies as they were affectionately known) at ILC assembled the Chromel-R EVA gloves in layers over what appeared to be a IVA glove: each EVA glove was essentially bespoke.I'd imagine that would preclude the outer layers being donned and doffed separately from the IVA glove. |

Ulli is better versed on this, so I'll defer to his knowledge. (What led me to suggest such was a too quick response to seeing a "back-up" pair (left, right) of EV gloves for Alan Bean in the Smithsonian's collection catalog. On second look, there is no mention that these back-ups flew.) |

Similarly, what led me to think that maybe they were removable covers were a pair of EVA glove covers without the bladder on the Smithsonian website. |
