In reply to pff: I also find I cant sleep properly in a mummy bag so use a Semi rectangular bags from Western Mountaineering for treks and base camps. Then a mummy shaped one above Base Camp where you aren't going to sleep very well anyhow.
I think Western Mountaineering are better made than PHD and have at least as good materials and down and I have sleeping bags and jackets from both.
The quality of the stitching is better. At times PHD remind me of Paramo in terms of workmanship.
Both are good, just for the price, WM is better.
