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

In the past, drafty cabins and frosty tents may have kept you from a good winter 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 (your travel partners would prefer that you shivered). Stuffed full of Integrity synthetic insulation like a turkey's stuffed full of, well, stuffing, the Farwell will keep you warm all the way down to zero degrees, making it a top option for icy winter hut trips and camping expeditions where going superlight isn't necessary. Synthetic doesn't pack quite as well as down, but it compensates by retaining its warmth even if it gets wet and staying well-lofted, so you don't have to worry about condensation turning your bag into a popsicle.

To reduce weight as much as possible, the Farwell forgoes insulation on the bottom of the bag, opting instead for an integrated sleeve that uses a sleeping pad as insulation, letting the bag pack down smaller than it otherwise would while the pad keeps you warmer than traditional insulation, which would only compress under your weight.  The Farwell also has winter-defeating features like a no-draft collar, zipper, and wedge, a pillow pocket, and comfortable nylon taffeta lining that will keep you deeply asleep, even if your tentmates start bashing you with shoes and headlamps to stop the racket.

  • 0-deree rating is designed for cold winter and fall trips
  • Integrity synthetic insulation stays warm even when wet
  • Rectangular shape
  • Soft nylon taffeta lining
  • No-draft collar, zipper, and wedge
  • No ground insulation―meant to be used with a sleeping pad for insulation
  • Integrated pad sleeve
  • Pillow pocket and hang loops

A good winter bag in my area

  • Gender:Male
  • Familiarity:I've put it through the wringer

This is my fourth Big Agnes bag. I've worked through so many trying to find a bag that will keep me warm at temperatures in the low 20s (about as cold as it gets where I camp). So, the 0-degree Farwell is, for me, comfortable in the low 20s. I love the Big Agnes sleeve & pad system and the quality of their products. The Farwell is super roomy which is great for me because I'm a side sleeper. I'm very happy with the bag, and if I ever needed another, I can't imagine it wouldn't be a Big Agnes.

What pad sizes work with this sleeping bag?

Pad sizes that work with each sleeping bag size:

Regular (Sleeping Bag): 20"x72" or 51cm x 183cm

Long (Sleeping Bag): 20"x78" or 51cm x 198cm

Anytime you have a Big Agnes question, shoot me an email and I'll make sure to work with you 1-on-1!

Warm to -10

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

I'm 6'6", 220 lbs and this bag in long is long and roomy enough for a restless sleeper like me. I've used it mostly for winter camping in PA and a few cold nights in Yellowstone with no problem staying warm and cozy. I sleep on a Big Agnes Insulated Aircore sleeping pad. I use another bag for warmer backpacking trips as this bag is plenty heavy.

Is this a discontinued bag? If so what is the replacement?

Hey Mike,

This bag was revamped for this season from the previous model.
