When the weather gets frigid and the forecast looks damp, the Saros 0F/-18C is equipped to keep you resting better. The Saros uses 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 an onsite cold chamber to create a W.A.R.M. fit that allows room for multiple sleep positions without compromising thermal efficiency. 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.
