Very handy - Mont Bell U.L. Down Vest - Women's

Although it is a thin-ish vest, it is perfect as an extra layer for downhill skiing because it can be stuffed in a quart-size ziplock, vaccuum sealed and stored flat in a pocket.
The only issue with the shapeless fit is that it not so snug around the middle, and hence has the potential to be a bit draughty.
