Wore these for several days on the trail in hiking in Patagonia where you can have four seasons in one day. The pants were super comfortable and warm, and provided great wicking. My one complaint--I had a little chaffing from the pants after day one. It wasn't anything to cry about, but it was annoying. I switched to Neve's three days later and was just as warm w/ no chaffing. These are very snuggly though. It's nice to put them on when it's freezing outside.
