Ideal for 3-season backpacking, the women's REI Co-op Zephyr 25 recycled sleeping bag is our top synthetic design—light, compressible, cozy, and now with recycled materials throughout.
  1. Women-specific design offers more room in the hips and a slightly narrower shoulder girth for the best fit and thermal efficiency
  2. 100% recycled synthetic polyester insulation is durable and highly compressible; the fill also retains some insulating ability if it gets wet
  3. Shingle construction on top provides uniform loft and prevents insulation from shifting and creating cold spots
  4. Offset quilt construction on the bottom optimizes bag/pad system warmth while reducing unnecessary weight and bulk
  5. Mummy shape is thermally efficient, yet roomy enough from shoulder to knee to ensure sleeping comfort
  6. Trapezoidal footbox gives room to wiggle toes and the baffle in the toe box holds extra insulation in place to help keep feet warm
  7. Hood, insulated muffler and full-length zipper draft tube keep warmth in and cold out; hood conforms to the head and can accommodate a backpacking pillow
  8. Zipper cover and internal antisnag strip combine for easy zipping
  9. Stash pocket under collar holds small essentials
  10. Differentiated drawcords allow quick hood and neck adjustments in the dark
  11. 100% ripstop recycled polyester shell offers durability with abrasion- and tear-resistance for years of use
  12. Durable water repellent (DWR) finish on shell helps keep bag from getting damp if it comes in contact with condensation on tent walls
  13. 100% recycled nylon liner is soft and silky for freedom of movement
  14. Nylon stuff sack are included
