The women's REI Co-op Trailbreak 30 sleeping bag is great for those breaking into backpacking and everything that comes with it. This bag gives the right balance of warmth, packability and weight.


  • Designed specifically for women, with increased hip room and decreased shoulder room for improved thermal efficiency
  • Water-resistant synthetic fill keeps insulating in damp conditions
  • Comfortable mummy shape gives you freedom to move while you sleep
  • Zippered stash pocket for convenient access to essentials
  • 3-panel hood contours closely to your head to keep out cold air
  • Face muffler and full draft tube keep out cold air
  • Differentiated drawcords (1 round, 1 flat) let you adjust the hood and neck easily in the dark
  • Offset quilt construction gives even coverage with no cold spots
  • Durable water repellent (DWR) finish on the polyester shell resists moisture and stains
  • Included stuff sack compresses for packing
  • 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


Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Our backpacking bags are rated for temperature according to an independent testing protocol: International Organization for Standardization (ISO) 23537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

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.
