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.

Who's right on the weight, you guys or North Face? 9 ozs is a half lb.!


Thanks for pointing out the weight discrepancies. The weights listed here need to be revised as those are the weights for the -40 Inferno. Just looks like a data entry mix up. I'll have our tech spec folks get that fixed.

Here are the weights for the two lengths:

Reg: 3 lbs 5 oz

Long: 3 lbs 9 oz

If you've got any other questions, feel free to hit me up!

The correct answer to the question is: "The North Face."

I asked the question having looked at the North Face site, obviously. So telling me what that site (I doubt you weighed them) says, as though I am clueless, kinda misses the point. I had a like interaction over some boots here, this stuff is not rocket science. It may be you guys who ought to be asking me questions, but I'm not giving up a phone number :)

If this continues I would like some brownie points.

Fill weight?

Thanks a lot.
