I am NOT recommending the Tarptent as a four season tent, it has very little insulating value, and is not designed to carry a bunch of snow.
I much prefer a wall tent, myself.
Gotcha BB. It looked a little thin to do much insulating. I usually do a 24 hour bonzai trip that late in the season where I go in at nite get a few hours of rest (usually just bring my bag, pad, handwarmers and tarp and build a fire) and come out the following evening. This looks like it could be a little nicer than that while being really light and easy to set up.
I have been using a Kifaru SuperTarp for several years and love it. By itself it works great for early season hunts and once winter sets in I add the Annex and Wood Stove. It weighs a pound by itself and about 4 lbs for the winter set up. For sleep system I use a Jacks-R-Better quilt and 2 pads (a foam base and inflatable top pad). Overall camp weighs around 3-6 lbs (depending on season) and I am able to use the same gear year-round (which saves money... to use on more tags!).
I have upgraded my shelter to a Lightheart Gear SoLong 6. I currently have a Western Mountaineering Badger 15 bag but thinking about buying a Marmot Plasma 30 or Montbell UL Super Spiral Down #3 for early season hunts to save over a pound. I currently use a Nemo Astro Air Insulated Pad but am considering a Neoair Xlite in a Large which will save me some weight too. As you can see after only one 7 day backcountry hunt for elk in Colorado I'm trying to shave as much weight as I can.
