RE: Hardcore Backpack hunting gear?
Don't discount a blow-up air mattress with down inside the chambers. I have one, it's like sleeping on a water bed, I love it. I think I have a Big Agnes model. I slept at 8000' in Oct. when it got down in the single digits and I was toasty warm. I also pack a lightweight flannel sleeping bag for the bag in bag effect. I've used it when traveling too, easy to crash anywhere when your comfortable.
