I wanted an extra pair of mittens before I set off for Spring Break in Vermont. I tried these a couple nights before I left, knowing that I would get a good idea how well they worked in 20 degree weather. They were fantastic! Normally my mittens work only freezing and above, but my hands were not affected at all when the temperature was below freezing. The inner-fleece, while I was a little worried, is actually quite warm. I also liked the fact that I could FINALLY pull my jacket sleeves over my mittens, because Ride doesn't make huge openings. I really like these mittens and I recommend them to anyone who experiences below freezing weather and wants to stay warm!
