With the appropriate undergarments this jacket is to use even at subzero levels. It is not completely wind and waterproof but light rain keeps them already stood. And when things get really wet the jacket is so thin that it does not soak with water. It is not hard and it dries quickly. Warming this jacket is just by the fact that it prevents the wind slightly.
What I find extremely annoying is the end of the zipper which pickst on child / throat hurts or. Because it would be really nice to have some protection between.
