My wife and I have this one from Montbell (http://www.montbell.us/products/disp.php?cat_id=33&p_id=2321027) and it kept us dry when we got snowed on at Burgundy col. It's light, waterproof, packs small and is fully seam taped. But I have to agree with Matt, as we bailed in the morning anyway. Had it started snowing earlier in the night though, we would have been drier than without.
