These are the softest pajama pants in the world. Jon has a pair that his parents gave him, and after hearing about their rave reviews, they bought me a pait too. Very nice of them. The pants are soft and warm, great to be wearing after running hard all night. It started to get cold as I was finishing my workout too, which was not fun, but made me run faster. I stretched, but now I am stiff and cold and sore. I will be better in the morning though.
