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.

Here's what others have to say...

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

Best Answer

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.

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.
