I’m looking for a new Car camping/hunting cold weather bag. I already have a mummy bag for hiking but am wanting a roomier bag for camping. My wife will be using it for cold weather camping and she’s always cold so I’m thinking something around -12 would work. She gets cold in her 0 degree mummy bag when it’s 7 out. I’ll use it when I tent on hunting trips. Does anybody have any experience with the canvas bags Cabelas sells? Any stores I should check out?

thanks.
