The 3-season REI Co-op Igneo 17 mummy bag doubles down on protection with water-repellent down and waterproof/breathable fabric panels to create a premium, fitted backpacking bag for wet conditions.

  • Features

    • With a European Norm (EN) lower-limit rating of 17°F, this bag is suitable for 3-season use
    • REI double-protection design combines a polymer-coated down fill with waterproof/breathable fabric at the hood, sides and footbox—areas likely to touch a damp tent wall
    • Water-repellent 700-fill-power duck down offers superior loft and warmth and is certified to the Responsible Down Standard (RDS) and bluesign® approved
    • Ripstop nylon shell also uses a durable water repellent (DWR) finish to further protect the down fill
    • Performance fit keeps weight low and thermal efficiency high; regular length weighs just 1 lb. 15 oz.
    • REI in-the-round design puts vertical baffles in the sidewalls to wrap you in warmth and create a better fit than bags that use only horizontal baffles
    • Contoured hood, insulated face muffler and full-length draft tube all work to keep warmth in
    • Differentiated hood and neck drawcords simplify adjustments
    • Most REI backpacking bags can be zipped to other REI backpacking bags; women's bags zip on the right, unisex on the left
    • The REI Igneo Sleeping Bag includes a nylon stuff sack and a large cotton storage bag
