Most Packable Lightweight Running Jacket Ever?

It's Salomon but I don't know its name. I also know it will be £80 and released in January 2013. This must be right up their with the most packable and lightweight jackets ever made. It even works! It has climawind to keep the chill out and DWR layer to help in light rain conditions. It even kept me warm 2000m high in the pyrenees. Before I put it on a seriously doubted whether it would actually do anything, I was wrong.
