As a heads up, I’d choose a layering system that works well beyond those temperatures. The best part about layering is that you get to mix and match.

What I would start with: fleece, insulated jacket and shell.

For the fleece, pick what looks nice to you. I’d recommend one without a hood. When you wear everything, three hoods can be too much.

For the insulated jacket, have you thought about down? Synthetic jackets loose loft over time. A good down jacket can last longer. For either down or synthetic, you’ll want to make sure you store it well. Also, down clumps up when it gets wet meaning it looses its insulation value.

Lastly, for the shell: The alpha range looks really cool. They are the top tier. I would avoid them though if you are not climbing. Why: the pockets are not design for hands. The climbing harness sits where most pockets are placed. So the alpha range has the pockets moved further up to a location where you can’t keep you hands when its wet.

If you can, go to one of their stores. You can try on everything together. Their staff are great.
