This monkey pants

Finally, something on eBay I actually need.

"It's offered to your attention the 'space pants' for macaque small monkey to wear it during the experimental space flight. This pants has been used for animals (monkeys) experiments in 1950s & 1960s in the USSR Institute of Biomedical Problems (IMBP, Moscow). This monkey's 'space pants' are designed with many clasps to fit bigger or smaller monkey."

I must write to the USSR Institute of Biomedical Problems to see if they have any more. This pants is hot.
