A roomy bag that ensures you won’t shiver through any more cold fall nights.

In the past, breezy cabins and frosty tents may have kept you from a good night’s sleep, but now that you have the Big Agnes Farwell 0-Degree Synthetic Sleeping Bag to burrow inside, you snore the nights away. With the help of the Farwell’s bottom sleeping pad sleeve, which secures your pad so as to insulate you from the frozen ground underneath the tent, you can find the comfort you left back in civilization inside this highly insulated, roomy rectangle.
  • This Big Agnes bag requires a 20-inch-wide sleeping pad (sold separately) for it to be completely insulated, which makes the bag lightweight and more packable
  • The tough, outer nylon ripstop shell features a water-repellent treatment to keep the frosty dew out
  • Lightweight, synthetic insulation (made from 97% recycled materials) keeps you cozy as the temps dive and works after it gets a little damp
  • An insulated draft collar around your head and a draft tube covering the zipper provide extra protection to keep you toasty despite the cold
  • Two levels of insulation—one as a base next to your body and the other to add loft—mean that the bag traps more heat
  • Built-in pillow pocket holds a fleece or pillow for an enhanced night of rest
  • Interior fabric loops allow you to add a sleeping bag liner during colder spring and fall nights
  • A 70-inch YKK #8 zipper down the left or right side of the bag lets you zip it together with a compatible Big Agnes bag (sold separately) for a warm night with a camp companion

My third try for a winter bag...

  • Gender: Male
  • Familiarity: I've used it several times

...and with previous experience with Big Agnes' rating system, I knew good and well it would not be a "0 deg." bag, but instead probably warm down to the low 20's which is all I need here in Texas. I nearly froze in a Big Agnes Gunn Creek (rated to 30) in the 30's, and again in an Encampment (rated to 15) in the low 20's. I even tried stuffing the Encampment inside a summer bag (a Big Agnes Cross Mountain rated at 45) in the hopes the combination of the two would have an additive effect; it was even colder.

So I figured the Farwell, rated at 0, would sleep warm in the low 20's. Why do I keep trying? Because Big Agnes gear is well made, and I love the concept if the integrated pad sleeve and the roomy design of these bags. I'm a side sleeper, and the semi-rectangular shape of this series is so much more comfortable than the mummy bags I've tried in the past. Suffice it to say, they run a little colder, so the temperature rating Big Agnes assigns them is hit or miss.

So, I had the Encampment out on an extended motorcycle camping trip last month and slept very warmly (with socks and mid-weight fleece bottoms and top) when the temperature in my tent bottomed out at 26. It's a large bag, and probably not a good choice for backpacking, but this is not an issue for me. I think it's going to work!

Temperature Rating a HUGE disappointment...

I don't recommend this bag as it is advertised. It now sits in the trunk of my vehicle as an emergency sleeping bag along with the dual core sleeping bag I had purchased with it, as a 0 degree sleeping system. I used the tall version, as I am 6' 3" 195 lbs with an athletic body. It has plenty of room but in no way is this bag rated to 0 degrees. I spent a night in the Holy Cross Wilderness and temps got a s low as the low 20's throughout the night. How do I know? I was up most of the night cold and miserable checking my watch.

In addition the inside of the bag coupled with the BA dual core pad was like a slip n slide all night. Any slight angle and you had to constantly adjust yourself as you would slide to one side of the bag. It was a good concept by BA but it needs more thought. I'm tempted to drive up to Steamboat and dump this on their doorstep.

Don't waste your money on this one, unless you plan on using for car camping in 20 degree weather or higher.

I'm going back to MontBell down fill and a separate pad and sleeping bag system. Sorry Big Agnes. I wanted it to work, I really did... :(

Thats interesting??? I have this very same bag and use the 15 degree air core mattress. I have slept outside with temps dropping to around -2 for a night time low and barely felt a chill. The ground had snow on it so that actually made my 15 degree air core mattress sufficient because the snow acts as an insulator as well. I usually do a few winter backpacking trips each year and had around 2 weeks worth of nights total from last winter where temps where anywhere from 15 to -2 for a night time low. I tend to run a few degrees warmer than most people it seems. Im in a tshirt and boxers in this bag up till about the single digit lows then I might opt for long underwear. I found this bags temp rating to be very accurate....

What is the R value on your pad? If you do not have a sufficiently rated pad for the type of camping you do you will need an even lower rated sleeping bag. The sleeping pad is usually one of the most overlooked pieces of equipment. When a lot of people get cold in their sleeping bag they usually blame the bag which is not always the case

A sleeping bag. I slept in it.

Okay so the picture doesn't show it unrolled, but the product image honestly says it all, really no need. However, I did want to show what my set-up was: a tarp, an Exped 26 incher, and an ultralite Z mat (which was what slid into the Big Agnes's bottom...and hopefully the only thing (hah)).

Scene setting:
Weather was calling for 28 degree lows at night for the area code we were hiking in.
don't assume area code forecasts are relevant to people outside of the developed town

Scene setting:
the wind was bitterly raking across the mountain all day
I wanted to test the sleeping bag (and exped mat)'s temperature rating by sleeping out under the stars.

Climax and Conclusion:
We hunkered down behind a slope to block us from some of the wind, sparked up the fire, watched our breath and dried our socks.

The technology we had said it was 22 degree's out, without accounting for windchill. I planned for 25 degrees, but thankfully I had just bought the ZERO DEGREE sleeping bag, it should keep me perfectly warm....tentless.

We got to sleep about an hour after dark. I was that giddy kind of happy getting into this sleeping bag. It was cold out, and I knew as soon as I warmed up some of the inside I'd be in heaven. With two layers of loose fitting long underwear and a pair of wool socks on I was going to sleep great!

I woke up at 1am, what little hole was left in the face area I just couldn't cover up. Happily, I wiggled around in the enormous amount of stretching space this bag provides, pulled my jacket over my face and got back to sleep.

4am I woke up from some rustling, turns out my compadres had to get up. Their 30 degree sleeping bags weren't holding any heat, and their super-lite solo tents had iced over inside. They were starting a fire so we could get a couple more hours. Although I wasn't as cold as them and the internal sleeping bag temperature hadn't reached a dangerous level, it was getting quite uncomfortable and I knew I wasn't going to be able to sleep. Needless to say, I stayed in it for another hour, then got up and guzzled tea by the fire. Damn that tea was delicious.

As for the sleeping bag, I originally wanted to give it 3 stars. The only thing I was missing was a tent, which would have blocked the windchill...but there was no way the windchill brought the temperature near zero (later learned it was 18 at it's lowest). So I'm just a little tired of a rating system that is never accurate, by nearly 20-30 degrees every time I try one.

Also, this sleeping bag isn't really the "in your pack" type, as it won't ever compress enough to fit. It's just a big bag. And when attached to the outside of the pack, the fluffy loft is a magnet for thorns and sharp sticks. There needs to be a more rip/puncture resistant stuff sack if you expect hikers to use a bag that won't fit into the internal compartments of their pack.

But then I think about ingenuity of the bag, the fact that it's a U.S. company, and the fact that there are still ways for people who don't want to sleep mummified, to sleep comfortably on the trail. So even though the temp rating was a bit off, the bag got 4 stars and Big Agnes will be getting my future business just because I know no other bag I could have bought at this price would have kept me as satisfied as this one.

Wiggy is the only bag I've ever found that rates their bags accurately. I have a 5 degree back that kept me warm in Alaska when the temps hit 2 degrees with a 20 mph wind. I've used other bags (BIg Agnes for one) and you're right, they don't rate them accurately. Buy a Wiggys...they cost more but they are SOOO worth it.

with the sleeping pad, I have no issues getting it to fit in the lower section of my 80L packs. It is a fluffy bag, but with a compression sac or bag straps, you should be able to get it's bulk down to a manageable size. The only issue I have with my bag, is the fact that the zippers get stuck on itself, when you are inside, trying to get out.
