Insulated with water-resistant ProDown, The North Face Furnace 20 sleeping bag lets you sleep out under the stars without fear of a little damp, in temps below freezing.

  • Features

    • 600 fill ProDown™ is enhanced with a hydrophobic finish that improves warmth by allowing it to dry faster and repel moisture up to 10x longer than untreated down
    • Anti-compression pads made from Heatseeker™ Eco synthetic insulation are sewn into high-pressure areas that contact the ground to create an insulating buffer
    • Mummy shape fits the contours of your body to maximize warmth
    • Draft collar locks in body heat and provides a soft, comfortable feel around the neck
    • Vaulted footbox and fitted hood keep you warm from head to toe
    • Certified to the Responsible Down Standard (RDS) by Control Union, meaning that the ducks and geese that provide the down have been treated humanely


    Many sleeping bags are rated for temperature by an independent testing protocol. With both European Norm (EN) 13537 and International Organization for Standardization (ISO) 23537 testing, each bag gets a Comfort (or T-Comfort) rating and Lower (or T-Limit) rating. The Comfort/T-Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower/T-Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Ratings are based on a person wearing one long underwear layer and a hat, sleeping on a single 1 in. thick insulating pad. Many brands use the Comfort rating for women's bags and the Lower rating for men's and unisex bags. Everyone's body and sleep comfort differ, so EN and ISO ratings are simply a guideline to help you compare products.
