I bought these as under clothes for cold weather and they seem very warm and soft. I love the waistband because it isn't high and tight like the usual long johns. I feel they run a little big , but I have yet to wash them and see if they shrink. I bought a size small and my jeans are a 5 or 7 usually that's a medium. I am looking forward to being comfy and warm on my trip abroad to colder climates with these pants.
