REI Co-op Zephyr 25 Recycled Sleeping Bag - Women's

The REI Co-op Zephyr 25 Recycled Sleeping Bag - Women's is a women's synthetic mummy bag from the Zephyr 25 line. EN ISO 23537 testing puts its comfort rating at -3°C and its limit rating at -9°C, making it a colder-rated and more versatile piece of kit than a basic 3-season bag — closer to a shoulder-season-into-light-winter option. Fill is recycled synthetic polyester, the shell is 100% recycled ripstop polyester, and the liner is 100% recycled nylon, with a DWR finish on the outer fabric for moisture resistance. A draft collar and draft tube limit heat loss through gaps, and it's cut in a regular length for users up to 167 cm. It ships with two sacks — a compression sack for the trail and a larger one for storage. At 1588 g total, it's the heaviest of the three Zephyr 25 variants (kids', men's, women's), which tracks with its lower limit rating. It suits hikers who want synthetic insulation with a margin into colder nights and aren't primarily optimizing for minimum pack weight.
