When comparing the WM bison and the Marmot CWM, it seems both are great bags, similar weight, quality, etc. However, is there anyone who has compared them for shoulder, hip, foot girth, other than the numbers supplied by the companies? Roominess for a big guy in the long sleeping bag would decide for me which is more suitable.

This is a roomy bag. Seriously. 64" gives you enough space without feeling confined and not too much space so that you are wasting your heat trying to warm an oversized bag. I don't know about the Marmot bag dimensions, but you'll be very happy in the Bison!
