A premium, fitted backpacking bag for wet conditions, the 3-season REI Co-op Igneo 25 mummy bag doubles up on protection with both water-repellent down and waterproof/breathable fabric panels.
- With a European Norm (EN) lower-limit rating of 25°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
- Most REI backpacking bags can be zipped to other REI backpacking bags; women's bags zip on the right, unisex on the left
- Performance fit keeps weight low and thermal efficiency high
- 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
- The REI Igneo Sleeping Bag includes a nylon stuff sack and a large cotton storage bag
- REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
- Made in a Fair Trade Certified™ factory
- Contains materials that meet the bluesign® criteria
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. For REI Co-op brand nongendered sleeping bags, we provide an overall temperature rating that falls between the Comfort and Lower Limit ratings.
