Despite reading reviews that these were made large, I ordered the XXL. It is big on me, but I like the extra room. They are very warm and comfortable. I highly recommend them. Money well spent!!!!
If you can deal with a one piece long underwear set, then I would say these are the ones. I wore them to a Bills game the day after Christmas. The temperature was 15 degrees and it was windy. I like union suits. I wore them growing up in upstate NY and now have another pair to use in the construction trades. They did shrink up...I can shrink anything. So, think about that. I am 160 lbs and 5-8. They are a little full in the bottom but are not uncomfortable. The button front was OK. The back seat is awkward to re-button though. My eyes are not as good as they used to be......even the ones in the back of my head. I found them very comfortable to my skin with no irritation or aggravation whatsoever. I can get very itchy with wool. They really are nice and I am looking forward to putting them to the test on an outdoor construction site soon. I would say that they are everything that I expected.
