Sierra Design Sleeping Bags
I'm thinking about buying a new sleeping bag.
I just got back from an overnight camping trip. I have realized it is time to replace my sleeping bag. I've been doing some research this afternoon. I think I'm going to buy a bag from Sierra Designs.
Does anybody have any experience with this company? Or does anybody have a good suggestion for a mummy bag, that goes down to at least 15F?
I'm from connecticut. So we do some winter camping as well as late fall/early spring. I have a pretty ok summer bag. I am looking for a bag that will do ok for most most winter camping, but be really good in fall/spring camping.

Also i would like to take it on 3-7 day backpack. I have an internal frame backpack that supports up 55lbs of gear. It has a separate bag in the bottom for a sleeping bag. So size is a big issue as well.
So is the other bag (the 800 fill) take up smaller footpring (thus fitting in my backpack better).

Sierra designs is overall a great company--i've never used their bags however, just know their reputation...i can say that the bags dimensions (32inches across) will be a bit tight especially if you're a bigger guy..for reference, i'm 6'2" and weigh 200 lbs and would think that is tight....one last thing, 15 degress will be good for most winter camping but you'll sweat your head off in spring, summer and fall--and have to carry an unnecesarily heavy bag during those 3 seasons.....i think your best bet is to get a warmer 3 season bag (around 30 degrees) and get a liner for the occasional winter trip.
What is the best sleeping bag with at least a -20 degree rating?
I dont want a mummy bag. I want a compact rectangular sleeping bag. No more than 8 pounds. I want it to be a high quality sleeping bag without going over $250. One that will last for 8+ years while being slept in every night. I already know the difference of synthetic and Down bags. No need to explain. Thank You!!!

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.
