I like the Baker very much, but the Whelen (a small Baker) is a wonderful shelter for one (see the following link) using a fire for heat. http://tentsmiths.com/period-tents-whelen-tents.html
I now have an MSR Fast Stash which is much like the Whelen, but with a floor and screens, making it much more useable in many places (bugs seem to be an almost universal problem). I have yet to try it in fall to winter conditions, but I love the ability to lay in my bag and watch the stars or the nature I came to enjoy. Even in the rain. I can fix my morning tea and breakfast without leaving the bag.

Another super fire tent is the Forester (at least as I know it). This is also a one man tent although your head is toward the fire. After bug season it is a superior shelter for under a pound in light Eqyption cotton. One made with Sil-Nylon would be a pleasure to carry and use. The ones I see on line today are much bigger.

I have enjoyed both to much lower than reasonable temperatures. If you can build a fire, they will keep you warm much like Bruce indicated.

Bruce, is there an opening toward the front to let air flow through? How far down on the back does the plastic reach?

The cautions I would have with the SS as I see in the picture, are the likelyhood of fire damage to the plastic and the possibility of CO poisoning if it snowed.

Respectfully,

Jerry

In the link I gave above the Whelen Is MUCH TOO Large to be the tent I described. It is even larger than their Baker. To me the Whelen is a small tent, designed like the one in the link, about 4 to 5 feet high and 7 or so feet long. Just big enough to hold a person and their gear. Their Forester is also too big for a one person tent, sort of a crooked pyramid. The ones of each I have used have been one person shelters for packing. One of their important qualities was low weight. A pound or two of light cotton. Two poles or a ridge like shown above for the Whelen or three for the Forester, an inverted V for the opening and a pole down the ridge to the ground - about 7 or 8 feet long. JF
