Stretch out and relax after a long day in the roomy women's Big Agnes Torchlight 20 sleeping bag. Boasting an expandable panel that adds up to 10 inches of space, it helps you rest well in the wild.


  • 600-fill-power DownTek™ water-repellent down insulation keeps you cozy and warm
  • PFC-free DownTek insulation absorbs 30% less water and dries 60% faster than untreated down, and retains significantly more loft than untreated down after exposure to moisture
  • Contoured hood follows the shape of your head for a more comfortable fit; low-profile cordlock lets you uncinch the hood with one hand
  • No-draft collar and zipper seal out cold weather; insulated tube along upper hood opening keeps out drafts when cinched
  • Dual zipper sliders on patent-pending expandable panels allow you to make multiple fit adjustments or to expand overall bag circumference by 10 in.
  • Durable water repellent (DWR) finish on fabric resists moisture and stains
  • Interior fabric loops help you attach a sleeping bag liner (not included)
  • Exterior loops for hang drying or storage; includes storage sack and stuff sack for easy transport and stowage
  • Zip together left-zip and right-zip bags to make a double sleeping bag (additional bags not included)
  • Women-specific sleeping bag helps enhance warmth with a different fill weight and less-drastic taper from shoulders to feet


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.
