Don't "cheap out" on winter cycling apparel. Get the good stuff.
In terms of fit, I am 6'0 and 175 pounds and got a large and it is perfect. When I first put it on, the sleeves seemed long but that extra fabric covers the "reach" when your hands are on the handlebars. Perfect! The tail and extra pockets are handy as well. The media pocket is on the small side.
I like this so much I bought one for my dad for Christmas!
