The fit of the bag has been perfected in Thermarest's onsite cold chamber to create their W.A.R.M. fit that allows room for multiple sleep positions without compromising thermal efficiency. Our 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.
