Replying to Looking for a good shell/middle layer

So were I ski there isn’t alot of really cold tempatures and everytime I put on my coat to go shred I get a little too warm ao I started skiing with a hoodie but dont have any good middle layer coat and wanted to know if you guys had any suggestions. These days (atleast this season) most of the tempatures i had last season was around -10 so something light that keeps warm and that preferably has inside pockets to put my phone in etc. Thanks :)
