"After using fleece, down, and Gore Tex, my favorite piece of cool weather clothing is now a square-tailed medium weight wool shirt with a shoulder yoke, two chest pockets, and slash pockets in the front. It's breathable, warm when wet, and bug-proof.
It's a bit bulkier/heavier than my fleece products, but it has never let me down. I wear it over one of those black Smart Wool t-shirts(also wool) that this otherwise intelligent company discontinued."
