Get up to get down.

Your Rab Mythic 400 21 Degree Down Sleeping Bag won't drag you up the steep 10,000-foot slope to your summit, but it will make sure you get a solid night of sleep beforehand. Rab stuffed this lightweight bag with 900-fill hydrophobic down, a toasty combination that holds its insulation power even when you accidentally track snow into your tent. Pertex Quantum 7D fabric can withstand high alpine wear and tear and the compression stuff sack packs this bag down small so it's easy to haul between multiple camps.

  • Pertex Quantum fabric is super durable
  • 900-fill down is ultra toasty
  • Easy to pack at just over 1 pound
  • Compression and stuff sack included for easy storage
  • Item #RAB00HE
