Service was as promised. Thanks to Arcteryx for making such great, if totally pricey gear.
I wear it as a mid-layer layer underneath a Gore-Tex XCR shell over a midweight Marmot base layer.
One day skiing this spring, it was about
5F with a 15 knot wind, bringing it to below zero with the wind chill. The next day, it started cold and warmed up to the low 40's. I wasn't too cold, or with my pit zips opened up, it wasn't too hot. I could have used it as a cover layer in the afternoon, had I had time to leave my jacket someplace safe. Not to bad for one item, huh?
Plus, it fits well and looks great, too.
