It's very hard to keep the feet warm. And if the feet are warm then the whole body is warm. So these are great.Smells good, not too strong.Have 3 separate bags that stay warm - 1 on top, 2 on the bottom - covers the area well.Soft material.Matched description and color. Fits great size 9. Would probably up to 11.
