Inferno Sleeping Bag

Look to The North Face's Inferno Sleeping Bag for reliable warmth and protection in sub-zero conditions. Stuffed with lofty 800-fill down insulation, the Inferno has an extremely high warmth-to-weight ratio. The North Face treated this down with ProDown to retain its warmth in wet weather, and NeoVent Air fabric gives the hood, footbox, and back extra water-resistance.

A generous mummy shape lets you sleep in the Inferno without taking off your alpine apparel. The North Face equipped this bag with a cinch-cord at the hood to seal out the cold, a full draft collar to keep winds at bay, an internal pocket to insulate valuables and electronics, and a center half-length zipper for easier in-and-out.

  • Sleeping bag built for mountaineering and camping in sub-zero temps
  • 800-fill down has a -20F temperature rating
  • ProDown makes the down hydrophobic to retain warmth in wet weather
  • NeoVent Air hood, foot, and back are water-resistant and breathable
  • Adjustable hood and full draft tube block brisk breezes
  • Internal pocket protects electronics from frigid weather
  • Compression sack and storage sack included
  • Item #TNF01B1

Sleeping Beauty

Took this bag winter camping. In temperatures easily under 17 degrees.Felt like sleeping beauty. Because while everyone had a cold hard night. I was warm and asleep till I arose from a slobbery kiss from my sweet 4 legged furry friend.

Awesome bag for those frigid nights

Familiarity:
I've used it several times

This bag is top-of-the-line when it comes to warmth. The warmth to weight ratio is pretty awesome if you're doing some winter expeditioning (or just sleep really cold)! I'm a big fan of the middle zipper design, because it makes it super easy to zip/unzip without fumbling around trying to find it. This bag would be great for -20 to 10-15 degrees. Using this bag in 15 degrees gets pretty toasty though, so you'd definitely want to keep the zipper open to vent. Overall, a worth-while investment if you're planning on camping like a warrior in those freezing temps and actually want a good night's sleep!

Fire and Flames!

Familiarity:

This bag is the truth. One big tip would be to start warm for most effective use, but I found that when I got in it with the bag and my body already being cold, my body heated the interior in about 20 minutes. I was super impressed with this bag. It was easy to move around in, easy to zip and the mummy shape was perfect for me. I used the interior pocket for my phone to keep the battery from dying overnight. I used this on a 15 degree night at meadow hot springs and didn't wake from cold even one time. I would HIGHLY recommend a sleeping pad in combination with this bag. This may seem like a no brainer but if it isn't, an insulated sleeping pad dramatically increases heat retention. I woke up with frost on the entire outside of this bag but I was dry and toasty inside.It is also very light and packable for the warmth it provides.

Mixed, But Mostly Positive Review Here

Familiarity:
I've used it several times

Bag is super warm, high quality construction and packs down impressively small (get a different stuff sack than the one supplied for an even smaller bag). My girlfriend and I took these up on a winter overnighter on San Gorgonio in California. She had the -20 and I had the -40. We both really like the bags, although my favorite thing about the bag was her least. Their is quite a bit of wiggle room inside the bag. Lots of space to move your hips / knees around, sleep on your side, etc. I loved this, but my girlfriend found that all the extra space took her body a long time to heat up, and would have preferred a narrower cut. So anyone looking at these bags, keep that in mind. The other thing to note is the top zipper. We both actually really loved this design, and it makes the bag much easier to get in and out of (or cram a dog inside in the middle of the night). The zipper does have a down baffle covering it, but its fairly easy to accidentally flip the baffle the other way so its not doing its job. I think some sort of velcro system there would be a good idea, especially if you were using this bag down past 0 degrees. For the record it got to about 10 degrees when we were using it, and I got pretty hot and had to stick a shoulder out a few times in the middle of the night to cool off. My girfriend in the -20 was warm and cozy, not overheating like I was.

The name says it all!

This is the warmest thing I have ever slept in, period. It kept me toasty warm on a winter camping trip that got down to the single digits (I know it’s rated for lower but that’s just what the weather had in store that trip). I ended up unzipping it a bit as it was almost too warm when the temps got into the 20s, which leads me to be comfortable in saying that this bag would do excellent all the way down to -20. If you are looking for a top notch winter expedition bag, look no further. It even came with a large storage sack, a great storage alternative to the stuff sack (also included).

The Inferno!

Familiarity:
I've used it several times

So warm and cozy! I tested this bag out in the fall while on a fly fishing trip where the temperature dropped to 0 degrees along the river. I tend to be a cold human being were the inevitable happens that I wake up in the middle of the night because I'm freezing! This bag definitely lived up to it's name and I was able to sleep all night without waking up once. Sooo warm!

Lives up to the name

Familiarity:
I've used it several times

This shit is WARM! Imagine the puffiest down jacket you've ever worn, and then imagine sowing 12 of those together with multiple layers into 1 mega bag. Combine that with the softest internal and external face fabric I've experienced (except maybe the Cerium LT) and you have the Inferno Bag. With the weather I used this in I wasn't able to push the limits, but at 0 degrees I was more than cozy, and I generally sleep cold. I'd have no qualms taking this all the way down to -20f. I'm planning on a trip to Nepal and this is the bag I'd buy for the trip. Reasonable price and cozy as can be.

Pack is warm but has a horrible smell

Familiarity:
I've used it once or twice and have initial impressions

Oh my. This pack smells like the dead goose/duck is in the pack. What the heck. Is it warm and comfortable? Yes. But, could barely use it due to the smell. It never got wet either. Am I supposed to air this out for months in advance of use? It stunk up the entire room.
