Very warm and comfortable but waistband ripped open the first time I wore them. I don't recall catching them on anything to provoke the ripping and I highly doubt my 30 inch waist was too large for them. Good thing I have a mother around to sew them back up. Other than that great product.

How does the super-cold cotton bottoms compare to the super-cold polyester version in use? This description makes cotton sound the warmest, a polyester comment says poly is warmest, except for the Insulated Yukon. What is warmest for sitting in a chair in a cold room all day?
