Marmot Col EQ Long Sleeping Bag, rated to -20 degree F. I don't remember when I bought this, probably 15 or so years ago, before Marmot turned into the Ryobi of outdoor gear, while they still remembered they started as a great sleeping bag company and were making quality innovative gear.
I listened to someone who I thought knew what they were talking about and it turns out that even as a cold sleeper, I have hardly ever used this. I've probably tried 3 or 4 times and just ended up using it as a blanket of sorts, even in very cold temperatures.I remember this version, the long, was rated to a 6'6 height. I'm 6' and there is plenty of room in the toebox, plenty for a pair of boots or other similar gear, which was my intent. It comes with a stuff sack and with a larger storage sack that it can be stored loose in.
