How much?! Is probably what you're thinking, but it is money well spent! Lightweight, warm, windproof and well built. I have yet to come across weather bad enough to test its waterproofness fully but so far, it has kept me dry through short heavy bursts of rain, and longer drizzly periods. I wear it a lot for mountain biking as its a nice close fit, with good manouverability. I would almost say it is too warm, a decent base layer underneath is all I have ever needed underneath it. Truly an all round brilliant jacket, and Highly recommended!
