    Actually, you want a mummy bag with 800 fill down. Sierra Designs -20, $355. REI Expedition -20, $420. Marmot -20, $660.

    Silly me: I was thinking about a winter, lightweight backpacking bag. I do not know any climate where the temperature will be -20 degrees for 8 years every night. If you are looking for squatter sleeping bags, the price range is much cheaper, since the Forest Service crews will probably burn your illegal camp long before 8 years passes. Coleman Legacy Series rectangular, -5 degree, 13 pounds, $100 at Cabela’s, could be combined with a higher-rated bag or use the Cabela’s Boundary Waters rectangular, 650 goose down, 0 degree, 3. 5 pounds, $250.

    I want, I want, I want, I do too. Good, better, best is an opinion you will get a lot of that here I am sure of that. Read the reviews of the products you find on the web and form you own opinion of what’s “Best”. If you know the difference state your need completely down or synthetic.

    I like synthetics over down because when down gets wet it’s useless.
    therefore I recommend the Mountain Hardwear Lamina, add a fleece liner and your good down to -30

    You can find some -20*F bags, and you can even find a few that cost less than $250 and weigh under 8 pounds, but not rectangular. Slumberjack makes a -20*F rated rectangular bag, cost about $100, but it weighs nearly 11 pounds and is enormous to pack (15″x38″). The other -20*F or lower bags I’ve seen/found are mummy bags.

    What you might consider is a Campmor Goose Down 0*F rectangular bag, $170, 3lb-12oz, 9″x20″ pack size, plus a thermal mummy bag liner like the Sea-to-Summit Thermolite Reactor Plus (+20*F, 9. 3oz, 4″x6″) or Extreme (+25*F, $65, 14oz, 3″x5″). The total would put you at $235 and 4lb-10oz, and would also be more versatile when the weather was not so cold. A more commonly used option is to combine two sleeping bags with higher temperature ratings: a 40*F rectangular bag with a 20*F mummy bag inside would likely be good down to -20*F. This option gives you much more versatility for handling temperature variations throughout the year, and could be done within your $250 and 8lb limits.

    I’ve actually used the Reactor Extreme with an Adventure Medical Kit’s Heatsheets Bivy and no other bag, just Polartec pants, jacket and balaclava, and was reasonably warm overnight in a an improvised shelter (branches, tarp and pine boughs) while it was in the teens and windy outside (survival training exercise).

    No bag will hold up to 8+ years of daily use. Down bags, if always used with a liner, will last longer with occasional washing, but eventually the shell will fall apart. In synthetic bags the insulation will compress and collapse structurally, reducing its performance. My previous favorite 30*F bag started falling apart after 15 years of occasional use, probably 20-25 nights/year, and started losing its insulation performance after about 6 years.

    If you’re planning on living out in the wilderness, in a tent, for 8 years where temperatures can go as low as -20*F, you might want to consider some alternate ideas. As romantic as that might seem, it is unrealistic for many reasons. Ultimately, you will need some kind of maintainable, insulated and weatherproof structure, be that a grass or dirt hut, straw bale building, log cabin, etc. ; all of which would provide sufficient insulation and heating capabilities to avoid the need for an extreme temperature bag. Then there’s the matter of where you could stay for 8 years without ultimately getting evicted or arrested. There are limits on the number of consecutive days you can stay, and number of stays per year, on all public land. Even if you owned your own land or had permission to use someone else’s private land, there are usually local ordinances that prohibit long-term living in temporary shelters.

    I hate posting links, but this -25F sleeping bag by Grizzly has a sturdy cotton canvas shell and the softest flannel liner, with more features than you could find in any sleeping bag like huge draft tubes and chest baffles, double layer offset quilting, superior comfort and warmth, stuffed with Hyperloft Insulation, and stored in a custom Grizzly duffle with compression straps. Runs around $112. 00! Hope this helps you out!

    I want a minus 20 bag that comes with a porter to carry it and want them to pay me!

    Finding a rectangular bag with a -20 rating may be difficult, it will certainly be heavy, so will the price tag. I always recommend Marmot as one of the best made bags for your dollar.

    Why would you want a rectangular bag over a mummy bag? If you are going camping in -20 degree temps, you want a properly-designed efficient bag. Rectangular bags are ok for car camping in the spring and fall, but it is an awful design if you actually want to stay warm. And hate to break it to you, but no bag, especially no bag under $250, is going to last 8 years of being slept in every night. The insulation will be compressed within a year to the point of being very poor, even if the shell materials and stitching hold.

    If you want a -20 bag you will have to go with a mummy. Rectangular bags just aren’t warm enough. Also, your price range isn’t close to reasonable. I think you will need to look in the $500 to $700 range. Also, where will you be camping where it is -20 all the time?

    The first one that comes to mind is the Marmut Col. I actually have its little brother the Couloir, which I absolutely love. It is less than 4 pounds. http://marmot. com/products/col_membrain?p=117,71
