INNERSY Women's Thermal Base Layer Soft Long Johns Set Mid-Weight Ski Top & Bottoms for Winter (XS, Beige)

I like these for the flat seams, the warm fabric, and the color options. I think they would be nice in a mock neck style too. Very nice!

I would usually wear a medium, but I purchased a large because I wanted the set to be a little bigger in fit. Unfortunately the large fits more like a small. I was also disappointed to find that the hem and cuffs aren't sewn at all. They're just the raw edge of the cut-off fabric. I can't imagine this will last for very long, so I'm glad I purchased this set on clearance. That said, it is very warm, and would be comfortable if it was the correct size.
