Mythic Ultra 360 Down Sleeping Bag - Black

Rab Mythic Ultra 360 Down Sleeping Bag


Mythical Warmth

Anyone can take 900-fill down, stuff it into a nylon fabric, and call it an ultralight bag, but the Rab Mythic Ultra 360 Down Sleeping Bag takes lightweight warmth to a whole new level. While they did use 900+ fill hydrophobic goose down, Rab also added their Thermo Ionic Lining Technology (TILT), which works to reflect UV and infrared radiation back towards you throughout the night, like many emergency blankets do, but in this case with more comfort and less crinkle. When combined with a durable 7D nylon face fabric, this bag stays under the one and a half-pound mark, giving you a three-season sleeping bag that can handle anything from cold nights in the desert to ultralight backpacking trips high in the alpine.


  • Ultralight sleeping bag meets a high-tech design for an all-around sleep system
  • 900+-fill power provides an incredible warmth-to-weight ratio
