Even though I live in california, it does get cold in the winter and these pants are game changers. In the past I've had flannel lined levi's which were decent but not compared to these. These are warmer, lighter and not baggy. They are windproof, but I have not tested the water proof feature. Nice looking too. Didn't give them 5 stars, because the care instructions were not in english, so not sure how to wash and dry them.See full review
