Nearly the same weight and packability as a down bag, the Marmot Cloudbreak 30 synthetic-fill sleeping bag features an innovative construction that keeps you warm from top to bottom.

  • Thermal R synthetic insulation has excellent loft with minimal weight; shell is protected by incredibly durable yet soft and light 40-denier micro ripstop nylon
  • Non-bulky Thermal R maximizes warmth while reducing the adverse effects of perspiration, condensation and humidity inside the garment
  • Wave construction, consisting of overlapping shingles of insulation throughout the bag, prevents cold spots
  • Body-mapping of insulation directs warmth to key areas and adds maximum thermal efficiency
  • Anatomic 3D hood envelops your head in warmth; Face Muff allows hood to be cinched snug without digging into face
  • Full length zipper with a snagless draft tube prevents fabric from snagging in the zipper coils
  • Trapezoidal footbox allows insulation to loft fully around your feet for optimum warmth and comfort
  • No more midnight drawcord fumbling—smooth, flat upper cord and hard, round lower cord make hood and collar adjustments easy
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
  • The Marmot Cloudbreak 30 comes with a lightweight stuff sack
