All the urban outdoorsman I talk with in downtown Denver swear by their Western Mountaineering bags. Lots of them say they won’t even zip them up even when it’s below zero because they get too hot.
I‘m not sure what the R value of a flattened cardboard box is, but that’s what they using for a pad. And, those guys aren’t using merino wool… they just add layer after layer of sweatshirts wino style during the coldest of nights.
Also, the GWS bags are highly water resistant. I heard one guy say he spilled a whole bottle of Mad Dog 20/20 on his bag after he passed out, and when he woke up - he was still 100% dry.
