Description

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
