Best cold weather sleeping bag?

The whole past year, I was looking for a warm high quality down sleeping bag for 4-season mountaineering, hiking, backpacking, camping andother outdoor activities. I have been looking to all well established manufacturers such as Mountain Equipment, Feather Friends, Marmot, Rab, Montbell, Mountain Hardwear etc. I have been comparing various models and I was still searching for other manufacturers until the point I came across the Cumulus website. I have compared several of their models and I came to the conclusion that the Cumulus Panyam 600 was the right piece of gear for me.
