Built for extended use in the Arctic cold, the light and feature-rich Therm-a-Rest Polar Ranger -20 sleeping bag was designed in conjunction with renowned polar explorer Eric Larsen.

Features

  • Ultralight shell and soft liner are made from 100% recycled nylon; shell and liner are certified to the Global Recycled Standard
  • Box-baffled construction is filled with highly compressible, PFC-free 800-fill-power Nikwax Hydrophobic Down™ that maintains loft
  • Nikwax Hydrophobic Down absorbs 90% less water and dries 3 times faster than untreated down—a big plus on long trips where periodic drying is required
  • Down is certified to the Responsible Down Standard
  • Drafts are kept at bay by extensive, overstuffed draft tubes that overlap to prevent cold spots when closed
  • Unique snorkel hood helps seal in warmth while routing exhaled moisture away from the bag to preserve loft; magnetic closure keeps cross drafts at bay and eases entry/exit
  • Cinchable draft collar helps keep heat in
  • A pair of side vents provide customizable temperature control—and free your arms while still in the bag
  • Antisnag YKK zipper ensures easy entries and exits and helps prevent tears
  • Insulated Toe-asis™ foot-warming pocket helps keeps feet toasty
  • SynergyLink™ connectors secure your bag to your sleeping pad to optimize the comfort and thermal efficiency of your entire sleep system
  • Interior stash pocket lets you keep essentials close to hand
  • External loops let you attach a quilt or blanket (not included) for more warmth
  • Compression and storage sack included

Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

Each bag then gets 2 ratings: 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. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
