"squeezes the body five times harder than medical support stockings"

I had to fit for a couple of weeks this kind of stockings on my wife's feet while we were expecting our twins. I can tell you these are no joke. They were so tight my wife could never put them on herself. I had to use special techniques and my whole strength to roll them up. I can't imagine how a suit 5 times tighter over the whole body would feel or how you can put it on. I don't see this as a feasible idea. Even more they affect the circulatory system (they are used to avoid blood clots in the first place) which can be very dangerous on long space missions.
