Proton hoody alternative?

I am looking for a breathable, synthetic mid layer or occasional standalone outer layer for ice climbing and hiking in New Hampshire.

I have looked at the proton hoody, but the $350 price tag is a bit off putting. I, however, like the jacket features.

I currently have a proton FL/lightweight which I like, but was looking for a bit warmer. Also have an atom HW/AR currently. I was looking for something that slots in between. Typically worn under a gamma MX with a smartwool base layer.

What alternatives should I be looking at to the proton hoody? Rab Xenair light? Patagonia nano? OR deviator? Others?

Thank you
