Saros™ 0F/-18C Sleeping Bag


To keep freezing conditions at bay, the Saros uses synthetic eraLoft™ insulation for cozy warmth.

When the weather gets frigid and the forecast looks damp, the Saros 0F/-18C is equipped to keep you resting better. The Saros uses Therm-a-Rest eraLoft™ synthetic insulation, which is quick-drying and weather resistant, making it ideal for backpacking and mountaineering in wet weather from spring to fall. The fit of the bag has been perfected in Therm-a-Rest’s onsite cold chamber to create Therm-a-Rest W.A.R.M. fit that allows room for multiple sleep positions without compromising thermal efficiency. Therm-a-Rest SynergyLink™ Connectors also integrate the Saros with your pad to ensure superior comfort with efficient warmth and the freedom to move as you like for the best night’s rest possible. The Saros is offered in three sizes and designed to fit both men and women. Compression sack and storage sack included.

  • eraLoft™ Insulation: Efficient and compressible, our water-resistant synthetic fill uses hollow fibers to reduce weight without sacrificing warmth.
  • W.A.R.M. Fit: With Additional Room for Multiple positions (W.A.R.M.) fit means this bag allows for various natural sleep positions while maintaining thermal efficiency.
  • SynergyLink™ Connectors: Integrate the bag with a pad for optimal comfort and thermal efficiency; removable for versatility.
  • Zoned Insulation: Maximizes warmth and saves weight by intentionally placing fill where you need it most.
  • Toe-asis™ Foot Warmer Pocket: Ergonomic toe box that rapidly warms cold feet in a pocket of warm insulation.
  • Quilt and Blanket Loops: Customize your sleep system by layering our quilts or tech blankets for increased warmth.
  • Additional features: Heat-trapping draft collar, full-length zipper draft tube, snag-free zipper, cinchable hood and external zip pocket.
  • Compression sack and storage sack included.
