    Crank up the heat.

    Just as its name would suggest, The North Face Furnace 0 Degree Down Sleeping Bag brings you fiery warmth and a cozy night's sleep in alpine environments where temperatures flirt with the negatives. Stuffed with 600-fill ProDown insulation, the Furnace provides a toasty cocoon in temps as low as zero, and even retains its warmth under wetter conditions thanks to its water-resistant design.

    An ergonomic mummy shape makes for a spacious yet packable design, while the anti-compression layer on the back composed of Heatseeker Eco synthetic insulation ensures there are no dead pockets of cold space. A draft collar further prevents heat loss while sealing out blustery winds, and the vaulted footbox keeps your little toesies toasty without them feeling like they're in a straight jacket.

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

    Used a couple nights up in the Mt Hood National Forrest in late July. Was worried that a zero degree was gonna be too warm, got down to probably mid 50s and was great with the zipper about half open. The fabric and down are really nice. One draw back is that it’s big when packed, needed to get a compression bag to make it manageable, especially for backpacking. Would definitely recommend.

    Awesome bag!

    • Familiarity: I've put it through the wringer

    I used this bag on my NOLS trip which happened in the late fall. This bag kept me toasty warm every night I was out, which was up to 20 days at a time. Slept in high alpine snow storms in September, and snow storms in desolation canyon in November. This bag didn't flinch. I slept comfortably warm every night on my Therm-a-rest Z-Lite pad. The bag packs down smaller than I thought and the down didn't bunch even after getting soaked in the tents condensation over night. Would highly recommend this bag to anyone looking for a comfortable and capable solution to sleeping warm.

    Awesome bag!

    0' degree down. Fluffy. Bomber.

      Love this 0' down bag. This bag and the Marmot Ouray 0' bag are my favorite 0' down bags under $500. I'll be using this extensively in the High Sierras and the Sawtooth Mountain range this 2018.

      regualr length does NOT Fit 6ft

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

      I just purchased this bag to upgrade from my marmot tresles. I got the regular length im 5'11". The specs say it fits up to 6ft. that couldnt be more wrong. i used this bag on a 7 mile hike. when i went to get into my bag my feet were abruply stopped by the bottom of the bag. I had to force the hood over my head leaving the bag strecth from one end to the other. super bummed i already took the tags off now i have to resell and probably loose money even though ive only used it one night. Other than the bag being short , it was incredlby warm. temps got down to 28 degrees and i was not cold one bit. furnace is a good name

      Awesome bag.

        Just got back from Mt. Kilimangaro with this bag- it was amazing. I literally never zipped it up because so freaking hot- even on the last night at base camp where everything froze. This bag is no joke.

        Plenty warm for Alaskan spring.

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

        I bought this to use for a week-long, mid April camping/fishing trip to Yakutat, AK. It didn't get as cold as I thought it might with lows in the low to mid 20's (F). This bag handled those temps easily. At no time did I even begin to feel chilled. One gripe I had was the zipper would catch the inner liner. Once you realize you need to clear the zipper path as you zip the snags were reduced - but not eliminated.

        Plenty warm for Alaskan spring.
        Unanswered Question

        I’m 6ft 1/8” tall. Realistically, do I need to get a long zip? Or can I squeeze into the reg.
