I've been super happy with this $50 coleman mummy. Got it for $40 on Amazon Warehouse because the cardboard packaging was a little squished. Bag itself was/is perfect.
Use this combo to stay warm and comfortable down to 0 degrees in your car. The Coleman sleeping bag is rated at 0 degrees, but that's the survival rating. To make it the comfort rating add the Coleman liner and one of those $9 red Walmart sleeping bags.
