These leggings are super duper soft and as comfy as pjs. I've bought several different brands of fleece-lined leggings and they all pill. These haven't so far. The only thing is, they have a really heavy chemical smell even after being washed a few times. Hoping that will wear off. I like that these aren't thin - they are fitted, warm and soft. I'm 5'2 125 and they fit comfortably.
