Developmental white spacesuit Thermal Micrometeorite Garment (TMG) boot covering, measuring approximately 12.5 x 13.5, featuring an open bottom with a zipper and Velcro at the top. In fine condition, with scattered staining. Item has been additionally verified by an ILC Dover company historian. International Latex Corporation (ILC) produced the A7L spacesuit used throughout the Apollo program and continues to develop spacesuits for NASA to this day. This TMG is unlabeled and so likely made by ILC as a development model or prototype and potentially used in the ILC test lab to evaluate ways to reduce wear to the toe area since a Chromel-R patch is stitched to the toe unlike any flown boot TMG. The Thermal Micrometeorite Garment is the outermost layer of the spacesuit and provides insulation, radiation shielding, and protection from micrometeorites that could otherwise puncture the suit. This silver material, also used on the EVA gloves and lunar boots, cost an astronomical $3,000 per yard in 1968.
