I bought these base layer pants (size XS for my height of 5ft 2" and weight of 100lbs) to wear on my trip to Utah to wear in December. It replaced a really thin one I had previously bought at a big department store that just wasn't warm enough. I wore it under my regular clothing for sightseeing and winter activities throughout the trip. It's a good middleweight with good 'mobility', although I could probably do something even warmer. I didn't find them itchy. Overall high quality and comfortable. Very expensive but I'll probably use them for the next 20 years if they last.
