Looks sweet. Looks like a higher tech design for less dough. I had looked at them earlier and 2 things shook me off. I'm not crazy about the "mummy" shape (although I have a hunch for an average sized guy like myself your bag would have plenty of room to toss about) but what really dissuaded me was the 15 degree rating. I run "HOT" anyways and absolutely hate being to hot when I'm sleeping. I've never had a down bag..........do they breathe better and thus less likely to get sweaty or is that just "pie in the sky" wishful thinking??

If you do strictly summer trips, a lighter bag might suit you better, but overall I've had little problem with getting overheated.  I will zip it down and uncover as much of my upper torso as necessary to regulate the temp.  Some nights, I sleep on top of it if it's really hot and humid.  If you have a sleeping bag liner, that's a good way to stay covered without getting too warm.

As far as the bag shape, I had the same reservations going in since I'm a tosser and a turner.  The semi mummy shape still allows me enough room to toss around.  Matter of fact, it's almost easier since the sleeping pad slipped into the pocket on the bottom of the bag keeps the bag from wrapping you up in a knot as you toss.

It's really an amazing system that can't be fully appreciated without trying it.  It's one of the few things I've bought in my life that I liked way better than I thought I would.
