My husband is always cold in the winter, but these pants kept him warm even through our once-in-a-century freeze. He's worn them every day (alternating 2 pair) since the first of November to work outside, cutting trees, tilling gardens, building things. He gets them filthy but they wash and dry great. They still look like brand new despite how hard he is on them. He liked them so much he bought a pair for his 90 year old mother who is also always cold.
