I was browsing walmart today when I saw this really cheap mummy sleeping bag rated for -5F. The link for it is down below but I was curious if this is worth getting for camping? Not sure if it's down or not, which is important to me, but it looks like it. Does anyone here have it and if so, what do you think of it? For those looking at it now, what are your thoughts? Do you guys think that this would keep you warm in cold temps?
