    Keep the fire burning.

    Your classic down sleeping bag may be fine for the dry climes of Colorado, but when you head to the damp forests of the Pacific Northwest or the misty mountains of Appalachia, you're going to want something a little more water-resistant. That's where The North Face Furnace 20 Degree Down Sleeping Bag comes in. Light and compact enough for backpacking missions, it's insulated with water-resistant down that's capable of keeping you warm in wet climates.

    ProDown insulation delivers the same lightweight, high-loft warmth as regular down, but it's treated to absorb less water and dry faster so your comfort isn't compromised in soggy situations. And since down tends to lose its warming powers when compressed too much, The North Face also added a thin anti-compression layer of Heatseeker Eco synthetic insulation to the bottom of the bag. It fills any gaps in loft to provide superior thermal efficiency, and it adds further protection from waterlogged campsites. And since none of these features compromise the Furnace's packability, it's still a great choice for backpacking when wet weather isn't an issue.

    • Built for backpacking in cold, wet climates
    • ProDown 550-fill down is treated to be water-resistant
    • Heatseeker Eco on bottom of bag improves efficiency
    • Less tapered mummy shape for superior comfort
    • Vaulted footbox offers space to wiggle your toes
    • Draft collar prevents heat loss
    • RDS-certified down from geese that weren't live-plucked or force-fed
    • Item #TNF037B

    great bag

    • Familiarity: I've put it through the wringer

    i bought a house with no heat and am still doing the remodeling--no heat yet. although i live in nm it does get chilly. this bag is wonderful. keeps me and two cats comfortable and warm.

    Warm and cosy!

    • Familiarity: I've used it several times

    Nice, warm and not too heavy. It's not the smallest one but I liked that my girlfriend and me wasn't cold in the night in mountains and that's the most essential thing! :) Also I want to admit very kind, professional and fast work of Customer Service during that purchase.

    Furnace is right

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

    This bag really is a little furnace. The down filling is amazing and this is my first real sleeping bag so far im very impressed. It packs up pretty small as well. Looking forward to getting some more use out of it!

    Down Sleeping Bag = Paradise

    • Familiarity: I've used it several times

    Used this sleeping bag all over Alaska and Canada on a month long road trip. Very collapsible and easy to transport. After every long trek we went on through the mountains, I would always look forward to getting inside for a nice warm nap. Definitely worth the price! Don't think I'll ever purchase another sleeping bag... so solid. Taken it all over Washington recently as well. Perfect for spring/summer mountaineering in my opinion!

    Great Bag and warm!

    • Familiarity: I've used it several times

    Used it camping this spring and it is excellent at holding in heat. It was comfortable and compressed down very small, but didn't take it down below 40 degrees.
