Women's Merino 250g Thermal Bottom
They are fitted and work well under clothes. Not too thin. Not too soft but not scratchy.
Great warm pants!
Kept me warm and so comfortable. Definitely buying another one!
These are very comfortable and warm. I am 5'8" and 165 lbs. and I purchased a large size. These fit great, not tight. I was surprised how comfortable they are.
