  • Sleeping Bag SynergyLink ConnectorsTwo flexible fabric bands keep your bag centered on your mattress. They eliminate problems with sliding, twisting and cold spots, yet still allow the head and foot to rotate freely and follow you just as they should. SynergyLink™ Connectors fit any mattress up to 25 inches (63 cm) wide.
  • Sleeping Bag Zoned InsulationThe Centari features box-baffled and shingled insulation on the top and sides to trap rising heat, with sewn-through insulation on the bottom to reduce drafts in extreme cold. This Zoned Insulation works with your mattress to provide maximum insulation, while eliminating extra fill that is typically compressed, adding little insulation value.
  • Sleeping Bag freedom of movementTherm-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.

Temperature Ratings

Therm-a-Rest sleeping bags are rated to both US and European Norm (EN 13537) standards. All ratings are developed from procedures and testing conducted by independent organizations in the US and Europe. Sleeping bags and blankets without hoods are not subjected to EN testing.

  • EN Comfort: At this temperature, a standard woman can sleep comfortably in a relaxed position.
  • EN Limit: The lowest temperature at which a standard man will be able to sleep comfortably through the night. This rating is relatively close to those commonly used in North America.
  • EN Extreme: At this temperature, a standard woman can survive for at least six hours.
