Used them last week (Dec-2019) in cold weather one day but then turned wet, snowy, sleet, etc. the next day. Had only one minor issue, my 79 year old knee caps got cold when sitting since the insulation got compressed against mt knees. I wish they had made them with a bent profile similar to the way gloves have a curve to form to your hand. My one piece motor cycle suit is made like that for sitting on a bike for long stretches without binding on the knees. I think I'll sew a pocket on the inside for a "Hot Hands" warmer packet for the next hunt in about a week.
