Why We Like The Inferno Sleeping Bag

The North Face Inferno 0-Degree Down Sleeping Bag insulates against below-freezing temperatures so we can enjoy the frozen world without icing over ourselves. Expeditions into the frigid parts of our planet can yield the most beautiful vistas and pretty huge feelings of accomplishment. They can also bring cold, sleepless nights and downright dangerous situations, so we pack a bag that can handle the conditions. Thermal-reflective fabrics and lofty down insulation keep heat close for our comfort and safety.

Warm sleeping bag

[This review was collected as part of a promotion.] Good warm sleeping bag- only problem is that the zipper tends to snag- otherwise seems pretty weatherproof

Incredible loft, spacious, small details need refinement

[This review was collected as part of a promotion.] BLUF: great, warm, comfortable bag; zipper snags a lot; face cinch cord device too weak. Just getting into winter camping in Minnesota. The Inferno 0 degree has excellent loft that expands as though it's being blown up! Just spent my first night out in it. Temps got down to 10 degrees F, and I was toasty warm the whole night, wearing lightweight top/bottom long underwear and light wool hat (started with wool socks on but removed due to heat). I'm 5'11", 165, with medium width shoulders. In looking at various other brands' bags, this gave a couple more inches of circumference at shoulders, hips, and feet - not so much as to create a lot more space to have to heat, but enough for me (a restless sleeper) to be able to comfortably move around. The regular length is long enough to be comfortable but I do wish I had a bit more length, though I don't know that I would want the extra 6" the long provides. I was able to place a bit of stuff in the bag with me, but it gets tight pretty quick so if you want to do that, I'd consider sizing up. The zipper goes about halfway down the bag. I was initially concerned about this, but it is still easy to get in and out of, and for a 0 degree bag, there's no need for any more venting than that would allow (it does have a double zipper so you can open the bottom half with the top zipped if you want to vent lower in the bag only) and ultimately with less zipper, there's less ability for heat loss through it though the zipper draft tube does work very well. Next though, as they say, the devil is in the details. The zipper snags the vast majority of the time. I found myself on the floor in the living room practicing zipping and unzipping just to hopefully limit the snagging and I did become marginally more successful (this is the only bad thing about this bag, and admittedly, it is pretty frustrating, though fortunately, the snags are easy to fix). A smaller detail that is a swing and a miss is that the spring loaded pincher device that holds the face area draw string when you cinch it tight to seal in your warm air has too weak a spring mechanism. You can cinch it down, but as soon as you move at all, the string pulls through the cincher device even though it is not depressed to the open position. I may just take the much more sturdy one from my 20+ year old Cat's Meow and swap them out (bafflingly ((pun intended)), the 20 year old Cat's Meow doesn't snag nearly as much so it would seem TNF has slid backwards with their zipper choices). Overall, I love the warmth and comfort of this bag and would recommend it, but be forewarned about the zipper (moderate issue) and cinch device (not a big deal).
