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??
