Description
The Rab Mythic Ultra 0°C is a down sleeping bag designed for those who prioritize minimum weight, maximum thermal performance, and extreme compressibility for fast & light activities, lightweight trekking, and high-paced alpinism.
With 900FP European goose down, L.O.F.T. 3D™ construction, and a lining featuring TILT technology, it offers an outstanding warmth-to-weight ratio within the premium segment. It is a bag clearly aimed at users who count grams but do not want to sacrifice serious thermal protection for spring, alpine summer, and light bivouacs.
Real technical performance
Within the Rab collection, the Mythic Ultra sits above the Neutrino range in its focus on absolute lightness and advanced thermal efficiency. The L.O.F.T. 3D™ construction with helical baffles minimizes down migration and reduces cold spots, while the TILT-lined interior helps reflect radiant heat back to the body with virtually no added weight.
The use of 10D Pertex® Quantum ripstop on the exterior keeps the overall package incredibly light and packable. This is not a bag for those who prioritize maximum durability or carefree heavy use, but for those seeking a premium, technical product tuned for moving fast in the mountains.

Comparison within the range
Compared to the Neutrino 0°C, this Mythic Ultra 0°C opts for an even lighter construction, higher quality down, and a clearly more premium product feel. Where the Neutrino offers more versatility and robustness for general alpine use, the Mythic Ultra pushes performance into the ultralight realm.
Within the Mythic family itself, this 0°C model is the most versatile option for mild to cool conditions. The colder-rated Mythic Ultras raise the thermal bar for more demanding environments, while this one maintains the most balanced profile for lightweight trekking, mountain thru-hiking, and fast bivouacs.

Is it for you?
Yes, if you are looking for a premium, ultralight, and highly packable down sleeping bag for moving fast in the mountains.
Yes, if you highly value the warmth-to-weight ratio and want a technically advanced product.
No, if you prioritize robustness, carefree heavy use, or better performance in sustained damp conditions. In that case, the Neutrino or synthetic ranges might be a better fit.
