Saros is a period of time used to predict an eclipse of the sun or moon.

Two flexible fabric bands keep your bag centered on your mattress and eliminate problems with sliding, twisting and cold spots. SynergyLink™ Connectors fit any mattress up to 25 inches (63 cm) wide.
The Saros features three-dimensional shingled insulation on the top, sewn-through construction on the sides, and a fabric-only bottom designed to partner with your mattress. 70% of insulation is placed in the top of the bag, 30% is placed in the sides, and the bottom is not insulated.
Therm-a-Rest sleeping bags are designed with extra room in the torso to allow your shoulders, elbows and hips to move freely. At the head and foot the fit is closer, keeping you warm while decreasing overall weight.
EraLoft™ is a proprietary blend of three synthetic fibers that provides superior warmth, loft and durability. Short, soft fibers trap warmth, long fibers create loft and medium-length fibers provide structure and water resistance.
