Being a rather large and tall person, I've struggled with finding good sleeping bags that actually fit. The North Face makes some good ones for big people but they're synthetic and kind of heavy. Lately I've been using Marmot down bags, they aren't as big as the North Face ones but they're down and way lighter. A little tight but they work. But I only have a 20 degree and 5 degree in that style and I need something for warmer trips. This past weekend, I ended up sleeping out on my tarp, no tent and no sleeping bag for much of the night. I just had my nylon convertibles, socks, and down jacket. I used my sleeping bag as a pillow. I woke up after a few hours and pulled it out but only because I was a little cold on my legs. So that got me to thinking, what could I do instead of a sleeping bag. I've searched high and low for a roomy 40 degree bag with no luck. So what about a down blanket or down pants or something. Or maybe an actual blanket of some sort. Any suggestions?
