    These are very nice. They are even long enough! So often thermal undies are too short and there’s a gap between sock and bottoms. Well made. Navy blue. I like the waistband too. Not scratchy or too tight or too loose. I would definitely recommend.

    The thermal underwear were not as expected. They were thinner than I thought they would be. The material was not as soft and comfortable as I was led to believe.

    This are silky yet warm, perfect for fitting under jeans when working outdoors in the fall or winter. Only issue is the fly is too small for a larger appendage. Highly recommended.
