A Genuine ITMG

ITMG stands for Integrated Thermal and Micrometeroid Garment.

The ITMG was placed over the pressure suit, or PGA (Pressure Garment Assembly) to protect the astronaut against the extremes of the space environment. There were 18 layers of different materials that made up the ITMG.

This ITMG was used by Fred Haise during backup training for Apollo 16.

There is a "Charlie Duke" nametag on the front, but the manufacturer's tag on the inside does however show this ITMG to have belonged to Fred Haise.

Front view of the A7LB ITMG. The holes on the chest are for the gas and water connectors.

Back view of the A7LB ITMG, showing the access flap, which starts and finishes on the front, but continues all the way around the back, splitting the suit in two when opened.

Side view of the A7LB ITMG.

Top view of the ITMG, with the access flap opened, the velcro released, and the top half doubled over.

View of the legs of the ITMG when it has been turned inside out, showing the grey neoprene-coated ripstop nylon liner. This was normally up against the exterior of the PGA which was worn under the ITMG, though the astronaut never had to put the ITMG on separately - it was ordinarily an integral part of the suit.

A closeup of the left shoulder, showing the pocket used for pens and the astronaut's torch. In this view, the flap of the pocket has been left open.

A view of the closed access flap on the right thigh. This flap covered two access points to the PGA.

A view of the opened access flap on the right thigh. The two points to the PGA were accessed here: the Biomedical Injection Area (left hole) and the UCTA Connector (for removing urine) (right hole).

A closeup view of the zipper on the left thigh. The silver ball on a short lanyard was simply designed to enable the astronaut to undo and do up the zipper while wearing bulky spacesuit gloves.

My hearfelt gratitude to David Mather for his generous assistance in agreeing to lend this item to me.

My thanks also to Jasjha "Dutch" Stel for his brilliant camera work!
