The Rab Mythic Ultra 180 is a unique ultralight Down insulated sleeping bag offering one of the best warmth to weight ratios out there thanks to its heat reflective Thermo Ionic lining. The Mythic Ultra 180 excels in lightweight multi-day mountain missions where every gram has to be accounted for.

The super lightweight 10D Recycled Atmos outer is DWR treated and downproof. Its incredibly lightweight nature ensures that the Down within will loft fully for maximum warmth. The Mythic Ultra contains 900 fill power R.D.S certified European Goose Down. The Down in the Mythic Ultra is treated with a fluorocarbon free hydrophobic treatment developed by NikWax to ensure that it retains its loft in damper environments. While extending the lifetime of the bag and ensuring its performance in a wider range of conditions this does not make the bag waterproof.

Rab's super light 10 denier Thermo Ionic liner on the inside of the bag uses fibers coated with titanium to reflect your own body heat back giving the Mythic Ultra a Rab Sleep limit of 0 °C, much lower than you would normally expect on a sub 500g sleeping bag.

The bag has a Mummy Taper shape, more tapered in the upper body/leg areas so it minimises weight and enhances thermal performance. The Mythic Ultra features trapezoid baffles throughout the main body which maximise the retention of down in position and also overlap to minimise heat loss. Inside the bag there is an anti snag zip guard to prevent the zipper catching on the lining when you are zipping it up in a hurry inside a dark tent.

The Mythic Ultra features an insulated collar and hood drawcord to minimise heat loss from the top of the bag. The foot box is angled with your feet to reduce cold spots by minimising the internal space.
