The REI Igneo 3-season premium backpacking sleeping bag features goose down insulation and a waterproof, breathable shell fabric for slaying cold nights in the backcountry.

  • Features

    • Tested by an independent third-party lab using European Norm protocol, the EN temperature ratings allow direct comparisons across brands with other EN-rated bags
    • Waterproof, breathable shell fabric is an ultralight, coated ripstop nylon designed to dissipate moisture from the inside, repel moisture from the outside and keep down dry
    • 800-fill-power goose down is efficiently distributed for maximum warmth and compressibility; ultralight polyester mini-ripstop lining has a soft hand-feel
    • Exclusive REI Down Fill Calculator optimizes the amount of down per baffle for the most warmth with the least amount of down
    • 60% of insulation is put on top of bag where it contributes the most warmth and loft
    • In-the-round pattern wraps vertical baffles around perimeter of sleeping bag, from head to foot, creating a 3-dimensional bag that wraps you in warmth
    • Performance fit saves weight by reducing girth at shoulders, hips and lower legs while increasing thermal efficiency
    • Baffle spacing is optimized to keep down in place and prevent cold spots
    • Multichambered contour hood, insulated full-face muffler, puffy interior yoke, and full-length zipper draft tube with ground-level seams all work to keep heat in and cold out
    • Trapezoidal footbox mirrors sleeping position for room to move and thermal efficiency
    • External chest pocket keeps small essentials—headlamp, watch, glasses—right at hand and easy to find in the dark
    • Includes nylon stuff sack and large cotton storage bag
    • Differentiated drawcords (1 round, 1 flat) allow quick identification, even in the dark, so neck and hood adjustments are a cinch
    • Any REI backpacking bag can be zipped to any other REI backpacking bag because of the consistent 63 in., No. 5, YKK zipper; women's bags zip on the right, men's on the left
    • Zipper is backed by a wide, welded fabric flap that prevents snagging
    • Pad loops provide attachment points to keep your sleeping bag and pad together, so you needn't worry about rolling onto the cold ground (straps sold separately)

    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.
