Not sure what size you are, but here is a super deal in a LG red/black XL--

I have the same jacket in bright yellow in L... wore it once this fall when it was about 45-50 with just a shortsleeve jersey underneath. Think it will be fine down to about 35 or so with a silk turtleneck or fleece pullover. It is not lined but is heavier than most of my other windbreakers.
