The three-season Saros sleeping bag is the perfect choice for backcountry trips that start with a shaky forecast. 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. To keep the Saros efficient, we built in ThermaCapture Seams to boost the bag's warmth without adding extra bulk. Our SynergyLink Connectors also integrate the Saros with your mattress 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. Stuff sack and storage sack included.
