Polar Ranger -20F/ -30C (4 Season Sleeping bag) (Regular)

A cold-weather bag with a trim, efficient cut to please alpinists, expedition climbers and skiers out on extended tours. It’s light, very compact and capitalizes on the modern tech of hydrophobic down, reflective lining, and an engineered toe pocket that traps heat around your feet. Designed with input from polar explorer Eric Larson, it incorporates expedition-worthy features like a snorkel hood, central zip and overlapping side vents.

  • 800 fill-power Nikwax Hydrophobic Down is exceptionally warm and retains less moisture than traditional down.
  • Down is certified to the Responsible Down Standard.
  • Reflective ThermaCapture™ lining traps radiant body heat to provide additional warmth without adding grams.
  • 2 removable stretchy SynergyLink™ connectors hold your mattress in place under the bag.
  • Synthetic insulated snorkel hood controls frost created by your breath and eliminates cross drafts.
  • Zippered side vents open to let you use your arms without getting out of the bag or vent heat if the temp warms up. Overlapping interior draft tubes prevent cold spots.
  • Snag-free zipper with full-length draft tube.
  • Toe-asis™ shaped toe box features an interior baffled pocket of insulation to warm your feet.
  • Quilt loops let you customize your sleep system by attaching a Therm-a-rest quilt or blanket over top to add even more warmth.
  • Includes a stuff sack.
