These are the weight and feel of a super soft sweat pant, with a modern cut.  I love the loose leg that's open at the bottom.  And the soft fleece next to your skin is heavenly warm - great lounge wear.  They would have gotten five stars from me if the waist band were less snug.  I wouldn't go up a size, the rest of the pant would be too huge.  It's as if the wide waste band were sized to fit at the traditional waste, but the rise is the lower modern fit.  They are too inexpensive to bother returning, and I may get used to the waste, or I'll adjust it somehow.  I'm mid-40s and appreciate the lower waste - I find anything that sits at my (traditional) waste is too uncomfortable.  I prefer a pant that sits on the hips, like these.
