Product Description

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