My blood runs pretty warm and I tend to get pretty hot inside most jackets with a waterproof-type membrane - but this one is just windproof. I can't ever get a feel for how well something like this breathes. How stuffy is this jacket?
Also...I am about 5'11" and 175-180 lbs or so - what size?
This is more of a style, wear around town jacket, and a warm one at that. It is hot and heavy. if you're looking for a jacket that breathes well during aerobic activity, get a softshell.
