REI Co-op Zephyr 25 Recycled Sleeping Bag - Women's
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.
- Women-specific design offers more room in the hips and a slightly narrower shoulder girth for the best fit and thermal efficiency
- 100% recycled synthetic polyester insulation is durable and highly compressible; the fill also retains some insulating ability if it gets wet
- Shingle construction on top provides uniform loft and prevents insulation from shifting and creating cold spots
- Offset quilt construction on the bottom optimizes bag/pad system warmth while reducing unnecessary weight and bulk
- Mummy shape is thermally efficient, yet roomy enough from shoulder to knee to ensure sleeping comfort
- Trapezoidal footbox gives room to wiggle toes and the baffle in the toe box holds extra insulation in place to help keep feet warm
- 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
- Zipper cover and internal antisnag strip combine for easy zipping
- Stash pocket under collar holds small essentials
- Differentiated drawcords allow quick hood and neck adjustments in the dark
- 100% ripstop recycled polyester shell offers durability with abrasion- and tear-resistance for years of use
- Durable water repellent (DWR) finish on shell helps keep bag from getting damp if it comes in contact with condensation on tent walls
- 100% recycled nylon liner is soft and silky for freedom of movement
- Nylon stuff sack and polyester storage bag are included
Imported.
Many sleeping bags are rated for temperature by an independent testing protocol. REI and the broader industry now use the International Organization for Standardization (ISO) 23537 protocol, which improves on the older European Norm (EN) 13537 standard; you may still see older items in our assortment that were only EN tested. With either protocol, each bag gets a Comfort (or T-Comfort) rating and Lower Limit (or T-Limit) rating. 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. Ratings are based on a person wearing one long underwear layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38. Many brands use the Comfort rating for women's bags and the Lower Limit rating for men's and unisex bags. Everyone's body and sleep comfort differ, and conditions of use (posture, clothing, sleeping pad R-value, wind, humidity, etc.) affect total insulation, so EN and ISO ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth.View all REI Co-op Women's Sleeping BagsBest Use Backpacking
