I am still searching for that perfect mid-layer jacket that is breathable and can be layered along with another jacket in 20s-30s weather. I layer a fleece pullover and then a 650 fill down-jacket. More often than not I end up sweating a lot because the fleece pull-over is not breathable. Need a jacket that is as warm as fleece but breathable. The search continues - I have already way way too many jackets and pullovers to count so I am not sure one more won’t raise eyebrows yes?
