The award-winning, Antares™ down sleeping bag delivers that performance in an ultralight package without sacrificing the warmth and comfort you need for a great night’s rest. Additional box-baffling now holds more loft and eliminates drafts, resulting in a new temperature rating of 15F (-9C). The change didn’t add any weight though, keeping the Antares a lightweight sleeping bag that can go the distance on the trail.

Antares is a supergiant star in the Milky Way noted for its visibility in the night sky.

  • Two 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.
  • The Antares features box-baffled insulation on the top and sides to trap rising heat, and a fabric-only bottom. 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.
  • Lightweight 750+ fill goose down insulation provides optimal warmth and compressibility. A 30D ripstop nylon shell offers lightweight performance and durable water-repellant (DWR) protection.

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.
  • Winner of an OutDoor INDUSTRY AWARD 2012, the Therm-a-Rest Antares sleeping bag was recognized by the jury for its degree of innovation and functionality, and was the only winner in the sleeping bag category.
