Confession: I do not work in any medical profession whatsoever. I bought these because I had a pair that a friend gave me from the hospital she worked at when they switched uniforms. They were so comfortable that I took to Amazon to buy another pair. They fit pretty well and are very comfortable to sleep or lounge around in. Not too hot, not too cold. I'm a big fan. The color is very true to the picture (speaking specifically for the hunter green variety.)
