I've been shopping for some time now for the perfect down jacket and this is it. The Pertex endurance fabric is light yet feels durable enough for some serious expeditions. There have been other jackets out there that are excellent like the marmot Ama Dablam but that doesn't have the Pertex endurance fabric that is nearly 100% waterproof. The fit is great but a tad bit large at the chest, then again I'm a small guy, but the small would have been to small to layer with. Its definately warm for the weight, and the price is okay for the quality your getting.
