If you'll notice, I have a

beside the die part, so I was being funny. I guess I should make sure and explain myself better. So I don't think I would've kicked the bucket that night, but I did do a lot of push ups to keep my body heat going. The problem that night was simple; I was pushing the limits of the quilt, but that's no different than what I do with a sleeping bag. The problem with the quilt? I couldn't button everything up like a do a sleeping bag....so I wasn't getting everything I could out of the system.
Here's a couple reasons I don't like a quilt as much as a sleeping bag.
You gain no heat from above your shoulders inside a quilt
Unless you're in a bivy, the wind will play hell on a quilt
If you roll to much, you'll get gaps in the system and you'll loose heat QUICKLY through those gaps
That doesn't mean I would never use a quilt again, as I think they are great at times, but again, I would never use one on a late season hunt. I like the fact that a sleeping bag has a draw cord that allows me to keep ALL BODY HEAT trapped inside....including head heat.
You can freeze just as easy in a sleeping bag when pushing the temp rating, but I've tested both 20 degree sleeping bags and 20 degree quilts, and there's no way the quilt keeps you as warm in the same temp.
So I will say again, THE SAFE BET IS A GOOD SLEEPING BAG, and I don't see how you could argue that!?
