Rock on with the Rockaway.

Load the Marmot Rockaway 20 Sleeping Bag into your backpack, and hit the trail.

  • DWR-coated shell material fends off light rain and moisture so your bag and insulation stay drier in inclement weather
  • Lofty SpiraFil insulation combines hollow fibers and denser, solid synthetic fibers in order to offer a balance of warmth, softness, and compressibility
  • Snagless draft tube won't leave you stuck when nature calls in the middle of the night
  • An overlapping series of internal insulation shingles creates the Wave Construction, which allows for more efficient use of insulation so you stay warmer without additional insulation that would increase weight
  • Easy-to-reach drawcords make adjustments a cinch when you're bundled up
  • Trapezoidal footbox matches the shape of your feet: wider in the toe area and narrower in the heel so you have more foot room and warmer feet
  • Zipper garages cover up the two-way sliders from the elements so they operate smoothly every time
  • Face muff features super-soft, irritation-free materials for optimal comfort when hunkering down
  • Item #MAR2279

Great late summer bag

    Used this bag on a weekend camping trip in Virginia. Very comfortable, not to heavy for late summer nights. Average temps were in the mid sixty. Slept very comfortable. Used with a sleeping pad in my Marmot Limelight 4P tent. No worries. Great sleeping bag. Highly recommended.

    Happy camper

    • Familiarity: I've used it once or twice and have initial impressions

    Im very happy with this bag which works well for my camping style. Taking it for car camping was plenty warm at 40degrees(haven't tried it at colder yet), the interior is soft to the touch, and there is plenty of leg room and room to move around. I had trouble with the zippers catching despite the zipper garages and had to be careful zipping up and down. I wouldn't recommend it for back packing because the synthethetic doesn't pack as small as down so it seems a bit bulky. All in all this is a great bag and I'm very happy with it.

    Luxury Sack!!

    • Familiarity: I've used it once or twice and have initial impressions

    Since I sent my 0 mummy bag back to northface for repairs I decided I should probably get a spring bag in case fire season starts early. One thing about this bag ITS BIG ( as I had expected). Being that it will be in my PG bag and I don't have to hike around with it this is not a problem...tried this out on a 27 degree night with a sea to summit silk liner....I was toasty. This is my luxury bag it is so comfortable and has so much room to move. If weight and compression size is not an issue for you this is a great bag. Recreational camping, weekend hike or fire camp use is def legit. get it,i got it,its good.

    Love this bag!!!

    • Familiarity: I've used it several times

    I've packed this bag with me on several backpacking/camping trips and absolutely love it! My most recent trip being a winter campout in freezing temperatures. I stayed nice and toasty and had plenty of room to move around in the bag. My buddy, who had a smaller mummy bag, was jealous of how much room I had.
