Alps and Peru. Climbing around. I`m usually climbing in an R1 and small windshirt when needed. Hardshell only comes out when absolutely needed.
Layers in summer alpine:
R1, Windshirt, Nano Puff Vest, Hardshell, Atom LT
It works for me. Just needing to replace my Hardshell and these 2 at such a nice price certainly are desirable. I also have an affinity for Patagonia.
I don`t need the burliest jacket, been known to switch out to a simple guide jacket on the rougher stuff. M10 seems like a better fit into my system me thinks.
