Light and compressible, this synthetic uses body-warming strategy.

The Marmot Cloudbreak 30 Degree Synthetic Sleeping Bag strategically places extra super-light and compressible Thermal R synthetic insulation at the body core and foot areas for efficient three-season warmth. A moisture-resistant shell protects all that toasty insulation while a draft tube, hood, and face muff fend off body-chilling drafts. Nearly as packable and portable as a down bag, the Cloudbreak gives you the advantages of synthetic construction, including added affordability.

  • European-tested (EN) comfort rated to 30°F for reliable warmth in late spring, summer, or fall weather conditions
  • Body-mapped strategically at core and foot area, lofty Thermal R fine-denier synthetic insulation provides efficient warmth, even when wet
  • Mummy shape keeps insulation close to your body but won’t restrict movement, so you can sleep comfortably
  • Durable, lightweight nylon ripstop with DWR resists water, wear, and tear for enduring performance
  • Head-hugging 3D hood and non-chafing face muff prevent brain-freeze and bone-chilling drafts when temps drop
  • Snagless draft tube prevents drafts from sneaking in through zipper
  • Two hang loops for convenient airing out and drying
  • Stuff and storage sacks included

Great Bag

A friend of mine recommeded the sleeping bag to me. I have used it several times, and look forward to using it every time. It holds up very well in cold temperatures. Strong material, great color, packs well.
