Late to this party but the
Kuiu Super Down Ultra has been an awesome mid layer for me. It weighs nothing (8 oz), packs up into minimal space, and is very warm and cuts wind very well. I’ve never experienced an article of clothing that provides that much good warmth in that small of a package. Fits well as a mid layer and it looks nice (solid color), I wear it over a t-shirt as an outer layer in the winter here
It’s markedly warmer that the Peleton 240. Together they really provide a lot of warmth
