Midlayers

[Slim]

Anto to answer an earlier question, I sometimes wear my Nano-air jacket (what Pata calls regular fit) over my Nano-air light Hybrid jacket (which has a slightly slimmer fit) and it works well.
To warm for me for skiing most of the time, but makes for easy packing for a trip.
Shell jacket + Regular Nonoair + light hybrid Nanoair. I can wear each on its own, or combine 2 or 3, so 5 or 6 options, spanning from spring to arctic.

An Ororo or other brand of electric heated vest or jacket makes my perfect mid layer. The vest gets worn just about every winter day for dog walking, and is always on me for ski trips. Not bulky, all day warmth, works for me.
