I am using these primarily while cycling, and they are extremely warm. The thumb is a bit tight though, particularly with the liners. I have been using them without the liners, because they are a bit looser that way, and plenty warm even without liners. Too warm unless it is in the 20s F or lower. Very wind and water proof.
Overall I am very happy with them, but the tight fit is something to consider. I ordered a M, which is usually my size. Probably could wear a L comfortably in these mittens.
