Marmot Cloudbreak 20 Degree Sleeping Bag -

Laugh in the face of long miles and cold, wet nights when you're carrying the Marmot Cloudbreak 20 Sleeping Bag in your backpack. Two types of ultralight synthetic insulation give this sleeping bag a 20-degree temperature rating, a weight of just under three pounds, and the unique ability to retain warmth even when wet. Marmot's engineers used 'anchors' of Thermal R Micro to add insulation at your feet and core, while the basic Thermal R insulation takes care of everything else from your ankles to waist and from your shoulders to head. Other features include a shell with a water-resistant coating, a hood designed for maximum heat retention and comfort, and unique baffles that utilize a shingle-like structure to eliminate cold spots inside. Aside from the more recreational-style Maverick or Rockaway sleeping bags, the Cloudbreak is the only 20-degree sleeping bag in Marmot's entire lineup (the standard temperature degree ratings are 0, 15, and 30). This sleeping bag is ideal for backpackers who want a lightweight, three-season synthetic sleeping bag solution or wet-weather campers who need something cooler than a 15-degree sleeping bag and who would rather not make the leap all the way up to 30 degrees.


  • 3D Hood construction keeps in body heat more efficiently
  • 3D Hood construction matches the natural contour of your head and neck, provides ample room for your face, and maximizes heat retention with minimal bulk
  • Nylon ripstop and nylon plain weave materials make the shell and lining durable, lightweight, and highly compressible
  • Shingle Wave Construction uses a series diagonal baffles to 'stack' insulation from head to toe (like shingles on a house) and to control cold spots in the event of insulation migration
  • Super durable yet soft and lightweight 40d micro rip 100% nylon fabric


  • Full-length zipper makes entry and exit easier than ever, and it allows you to vent at the feet if you get a little too hot at night


  • DWR coating allows the shell to repel light moisture and precipitation so your sleeping bag and insulation stay dry
  • Hybrid insulation technology combines loft advantage of 2.5-denier Thermal R insulation with the packability of 1-denier Thermal R Micro
  • Body-mapped, Thermal R Micro insulation 'anchors' are located closer to your feet and core to provide additional insulation precisely where you need it the most
  • Hybrid insulation provides massive warmth without the weight or size penalty that would otherwise come with this amount of insulation
  • Body-mapped Insulation Yields Maximum Thermal Efficiency without Added Weight


  • Snagless Zipper Tube blocks drafts from forming at the zipper and uses a design that won't get constantly caught in the full-length zipper


  • Velcro-free Face Muff - Keeps the Drawcord and Zipper Away from Your Face
  • Snagless Draft Tube - Has Heavy Oxford Cloth to Repel Biting Zipper Coils


  • EN rating is 32F for the lower limit (an average man’s comfort level) and 21F for the comfort range (average woman’s comfort level)
  • Ergonomically designed shape to minimize heat loss and at the same time provide for a comfortable night sleep


  • Two hang loops allow for easier "airing out" and drying of your bag
  • EN Tested
  • The Cloudbreak is ideal for late spring, summer, and early fall backpacking or camping in dry to mild climates
  • Stuff sack included for easy packing
  • Face muff keeps your face warm at night while still giving you room to breathe freely, additionally this face muff is free of the hook-and-loop closure that so often rubs against your face and causes discomfort
  • Velcro®-free face muff prevents abrasion and provides warmth
  • Contoured mummy shape minimizes heat loss at the head and feet while giving you room to move around at the shoulders

Marmot Cloudbreak 20 Degree Sleeping Bag Review:


I had a 35 degree rated sleeping bag but it just could not keep me warm enough during 40 degree nights. I tend to be on the cold side at night and this was the perfect solution. I now stay perfectly warm in temperatures in the low 30's. The bag starts getting a little warm in 60 degree weather but I can always use my lighter sleeping bag for warmer weather trips. I tend to camp in mountain regions where the nights get pretty cold.
The feel of this bag is of the highest quality and the fit of the regular is perfect if your under 6'. I'm 5'10" and have good wiggle room.
Overall I would recommend this to anyone who camps regularly in below 65 degree weather.
