Trying to find reviews for someone who has used this bag in a bivy setup with just a tarp and no floor? I know the inherent disadvantages of using a down bag, but for the money (less than 200 dollars) I really feel like this bag would suit my needs for a early hunt in August in UT, or a early Sept hunt in CO or ID. I don't want to break the bank buying a bag, and I've thought about buying a quilt instead, but don't really know where to find a quilt for a similar price point. Opinions and feedback are much appreciated. Thanks!
