This is my suite. We sleep on cots with a pad. Before I got my super thick -35F bag, I’d use my ultralight backpacking sleeping bag. During the summer, it sufficed, but when the leaves started to turn and colder weather rolled in, I found myself shivering.
Because the cook is the first one awake and the last one the bed, I’ve saved some time by getting that big fat hunting bag. I’ve been out there in -15F weather and don’t even bother starting my fire some nights because that bag is so toasty once I’m in it.
