A great choice for backpacking or camping, this roomy synthetic sleeping bag is easy on your budget, yet it's also feature-packed and built to last.


  • With a European Norm (EN) lower-limit rating of 27°F, this bag is suitable for 3-season use
  • Roomy, rounded shape lets you comfortably move around; hood retains warmth and is big enough to fit a small pillow
  • 2-way zip lets you open the bag fully for use as a quilt or unzips at the bottom for ventilation
  • Polyester synthetic fill offers all-conditions warmth; offset quilt construction prevents cold spots and stabilizes the insulation
  • Differentiated drawcords (1 round, 1 flat) let you adjust hood and neck easily in the dark
  • Draft tube behind zipper combines with a draft collar to seal in warmth
  • Inner pocket is handy to stow a phone, glasses, light and other essentials
  • Polyester shell is treated with a durable water repellent finish to repel moisture and stains
  • Bag is available only with a right-side zipper
  • The REI Polar Pod Sleeping Bag comes with a stuff sack and a storage bag
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags


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.
