Insulated with premium 800-fill Nikwax Hydrophobic down and employing a number of thermally-efficient and comfort-enhancing features, the Therm-a-Rest Oberon 0 Degree sleeping bag delivers ultra-lightweight 4-season backpacking performance.
Down insulation has long been renowned for its compressible properties and efficiency in delivering an excellent warmth-to-weight ratio. The shortcoming of down has been its susceptibility to the effects of moisture, losing much of its performance qualities when wet or damp. Nikwax Hydrophobic down insulation provides water-repellency that keeps the insulation dry longer and allows it to dry faster if it should become wet. More importantly, it maintains thermal efficiency even if it becomes wet, a quality that could traditionally only be found in heavier, less-compressible synthetic fills. Additionally, the bag has “zoned” construction, concentrating insulation on top of the bag so you have warmth where you need it most and saving weight by minimizing insulation on the bottom of the bag where it just tends to get compressed beneath the weight of your body anyway. A reflective ThermaCapture lining inside the top of the bag also helps to project heat back toward your body to help keep you warm. Together, these features grant the bag its 0 degree Fahrenheit temperature rating.
Other features include snag-free zippers, a tilted comfort-enhancing toebox, SynergyLink Connectors to marry the bag to your sleeping pad (pad sold separately), an oversized zipper draft tube to keep cold air from reaching the interior of the bag, additional foot-warming insulation inside the bag to address an area most prone to heat loss, and a zippered exterior pocket for stowing small valuables.
The Therm-a-Rest Oberon 0 Degree sleeping bag is available in your choice of Small (fits up to 5’ 6”), Regular (fits up to 6' 0"), and Long (fits to 6' 6") lengths. A stuff sack and storage sack are included.

Real Customer Reviews
- Outstanding sleeping bag.
Likes: Lightweight and really keeps me warm. Great color-easy to work with in a dark tent on a dark mountain top at night. Easy to pack and unpack. It was so warm, I thought they should change the name to "Miami Heat". Outstanding product!
Dislikes: Nothing, nada-this thing did everything it was supposed to do. If I could change anything about it, though, I would make it a little larger in the chest area (maybe make it expandable somehow in the that area). I am 5'9" and weigh 185 lbs, and still got a little "cramped" in it in the arms/chest area. And this is with the large bag...that's supposed to fit someone that's up to 6'6".
