Protective warmth that doesn't weigh you down.

The North Face's Inferno Sleeping Bag boasts an ideal weight for ultralight backpackers and enough protection for alpinists. The North Face treated this bag's light and lofty 800-fill down insulation with ProDown water-resistance to retain its warmth in wet weather. Neovent Air fabric adds extra water-resistance to the hood, back, and footbox for moisture-riddled tents.

A generous mummy cut helps you layer up before you go to bed, and the half-length center zipper offers easy entry. The North Face also added a cinch-cord at the hood and draft tubes at the collar and overlap to keep frigid winds at bay. This bag also features an internal pocket to insulate electronics and valuables.

Sea-To-Summit Ultra Sil Dry Compression

Was able to barely fit it in a Small size Sea-To-Summit Ultra Sil Dry Compression sack. Without some more "try" and "shoving" its hard to be able to completely roll the top of that sack down but, does get the overall size of the bag slightly smaller not by much. When I take it on actual backpacking trips I like to use this compression sack for the dry feature to ensure the down doesnt get wet. Would fit better/easier in a size medium though. The Small is what I use for my 20 degree work horse bag and this obviously has more down in it.

Love it! Light and Affordable!

I've used it several times

I was skeptical of this bag. The obvious difference is how North Face used one center half zipper to save some weight versus traditional zippers which run the entire length of the bag. I thought it would be uncomfortable compared to other traditional zipped bags but, far from it. It was just as comfortable and I was able to move around inside like any other mummy bag out there. I actually liked the way the center zip worked as far as allowing the bag to breathe. Its easier to unzip the center zip a little or all the way to dump some heat on warmer nights and ends up being more comfortable. Usually when you have to unzip half the bag to achieve this half my body ends up out of the bag in the morning because I am moving around in my sleep. Or worse, I end up waking up cold because more of my body than I intended to was out. Not with the center zip, you just get more room to do a sit up and throughout the night more of my body than I wanted to does not end up exposed to the cold. The coldest I was able to use this bag in currently was in the teens during a climbing trip in the desert over the Thanksgiving Holiday weekend. I started with the bag fully zipped and my head inside the hood and after the down warmed up a bit was able to unzip it 1/3 of the way and sleep comfortably all night. I was not wearing any extra layers, just Capilene 1 boxers and t-shirt. I have no doubt that this bag would keep my comfortable down to 0 degrees but, that is different for everyone. I tend to be a cold person though and I am sure it would work. The next big thing is the price versus the weight. When you look at some other bags in the market, you pay a lot more to get the same quality down in a similar lightweight compressible package. This is the huge win for me! North Face also has the means to re-stuff the bag after you use it for many years, so like other top end bags, its an investment. Comes with a storage and compression sack. Was skeptical and trying it out turned me into a huge fan! Please feel free to reach out via email or my direct line if you have any questions regarding this bag or other bags on the market, I would be more than happy to help!


Is there any way to vent the foot area?


What are the overall dimensions of this bag?


Tech Spec says it's a 0 degree bag, description says it's 16F. Which is correct?

Hey Jim, This sleeping bag falls under the 0 degree sleeping bag category. Sleeping bag ratings underwent a revolution a few years back. Traditionally, a bag's "comfort rating" pegged the lowest temperature at which the bag would keep an average sleeper warm. Thus, a "20-degree bag" was intended for air temperatures no lower than 20°F. Were these ratings infallible? No. Humans have varying metabolic rates. Women, on average, have been scientifically proven to sleep colder than men. Furthermore, the U.S. outdoor gear industry had never adopted a standard to determine such ratings, so manufacturers assigned ratings based on their own research. Temperature ratings were at best a guide, not a guarantee. The 16 degree specification you see in the tech specs and description is the European Norm Comfort Rating which refers to the lowest temperature at which the bag will keep the average woman warm. If you browse through our sleeping bags, you'll also see European Norm Lower Limit rating which refers to the lowest temperature at which the bag will keep a man, on average, warm.


Fill weight? How does this one compare to the MH Phantom 0F? Thanks a lot.

Martin, My good friends over at TNF were able to help me get this info for you. Fill Weight's are as follows: Reg: 1lb 13.3oz (831g) Long: 1lb 15.8oz (902g) The MH Phantom O (MHW2372) and this bag are fairly similar spec wise. The major differnce being the MH Phantom is 3 oz lighter and packs smaller. But packing smaller can also compress the down more so that will decrease the longevity of the MH Phantom.
