I live north of Chicago and riding in the winter is a challenge. I have worn these several times, they are toasty warm and a great when riding. They did not move around, or bunch up like winter riding pants do. I highly recommend! I did go one size up, I ordered a large - they fit great over just about anything - jeans, winter breeches, etc. The waist is very adjustable so I had no problem with the fit. I am ordering a second pair in case Horseware decides not to make these anymore! Great product!
