Replying to Is the DNA Rolando jacket a winter or spring jacket?

I would like to get the rolando jacket but i need something that's gonna keep me warm even at 0 degrees F. It looks like a spring jacket, but I cant really tell from the pics. Would the carbon rod be a better choice?

also, what is better 10000 Water/Windproof or 20000 Water/Windproof?
