The Marmot Rockaway 0 Synthetic 0 Degree Sleeping Bag uses high-tech fibers and layered baffle construction to maximize warmth and keep you comfortable during late fall and early spring backpacking trips when you can count on cold, possibly wet, weather. The Spirafil insulation will keep you warm even if high humidity and condensation team up with the cold temperatures.

  • Zero-degree rating and an EN lower-limit rating of -2.9 degrees Fahrenheit means this bag will get you through a night when temps drop below zero; you'll be able to sleep comfortably with temps as low as 11.1 degrees
  • Moisture-resistant Spirafil insulation combines three unique hollow fibers for loft and a super-low denier insulative fiber to keep you warm in extreme cold
  • Shingle baffle construction uses offset, layers baffles to increase heat retention without adding much weight
  • Mummy shape holds warmth close to your body, and a trapezoidal foot box helps maintain loft around the bottom of your bag so your feet don't freeze
  • DWR-treated polyester fabric offers an optimal weight-to-durability ratio and sheds moisture while remaining extremely packable
  • Nylon plain weave lining is easy to slide into and easy to sleep in
  • Insulated draft tube is easy to get in and out of, and it prevents cold air from seeping in between the zipper's teeth
  • Stuff and storage sacks let you pack your bag tightly for trips and then let it air out and decompress when you're back at home
  • Two hang loops let you air your bag out after (or during) trips
