I could not have ridden all winter without these tights. I leave at 515 am and some mornings it has been near single digits. These tights have kept me warm and although they are thick and stiffer than regular winter tights, I have found them pretty easy to ride in. I wish only that they ran a bit longer, as I am fairly tall. I bought them on sale and saved a bundle. I highly recommend them.
These tights fit well and are very comfortable to ride in. I sized up one size based on reviews and they were perfect. The front wind panels have a lot of stretch and flex which I really like, not like other wind resistant tights that feel much more constrictive. I'm finding these work for me in temperatures from 30 to 45 degrees - dry and raining - keeping me warm without being too warm. They have become my favorite cold weather tight.
