The Mythic Ultra redefines what it means to be ultralight. Using a world-first, heat-reflective fabric treatment, this is pioneering protection for those who need to make every gram count.
Revolutionising sleep systems, the Mythic Ultra redefines what it means to be ultralight. Combining cutting-edge technologies with world-class fabrics, this is premium protection for those who need to make every gram count.
Continuing to build on years of experience, the Mythic Ultra is the culmination of all our knowledge and experience. Made in Derbyshire, it has an exceptionally light but durable ripstop 7D outer that allows the 900+ FP Hydrophobic European Goose Down to fully loft, maximising warmth.
The construction of the Mythic Ultra enhances this ratio through the use of trapezoidal chambers and a weight saving baffle construction that prevents down migration. Features are up to expedition standard with an ergonomically designed internal collar and hood; YKK® zip with anti-snag zip guard; and angled foot box.
What is TILT?
The inner lining uses Thermo Ionic Lining Technology (TILT) which reduces radiative heat loss by reflecting heat back towards the body resulting in increased levels of warmth. This dramatically increases the Mythic Ultra’s warmth-to-weight ratio without changing the original fabric’s properties or increasing weight.
Rab uses ethical, responsibly sourced down from Europe.
We are masters of insulation.
