Product Description

The Mythic Ultra 360 Long by RAB is a lightweight down sleeping bag designed for cold‐weather camping and mountaineering. Its longer cut is suited to users up to about 200 cm tall, offering a snug fit that helps retain warmth in temperatures down to a comfort level of –2 °C for women and –8 °C for men.

Packed with 360 g of 900 FP European goose down, this sleeping bag balances warmth and minimal weight at just 666 g. The fluorocarbon-free hydrophobic finish on the down helps it stay lofted when conditions turn damp, while the 7D ripstop nylon shell and thermo-ionic lining (TILT) boost durability and heat retention. Together, these features make it easy to carry without sacrificing performance on cold nights.

In simple terms, 900 fill power measures how much air the down can trap—a higher number means more insulation for less bulk. The Nikwax hydrophobic treatment causes moisture to bead off the down clusters, preserving loft when humidity rises. The TILT lining reflects your own body heat back inside the bag, adding a few extra degrees of warmth without extra weight. And the fine 7D ripstop nylon keeps the shell light yet resistant to tears.

RAB says about the Mythic Ultra 360 Long

With its world-first heat-reflective Thermo Ionic Lining Technology, the Mythic Ultra 360 delivers pioneering protection for those who need to make every gram count.

For mountain marathon runners and high-end alpinists who need to travel light, the Mythic Ultra 360 is a game changer. Built from ultralightweight 7D ripstop nylon, it uses Thermo Ionic Lining Technology (TILT) to coat the fibres with titanium, helping reflect the user’s radiant heat back into the bag without compromising the fabric’s breathability. While that reduces the amount of down required for a given level of warmth, the angles of the bag’s trapezoidal boxwall construction also improve the evenness of down distribution, eliminating cold spots.

Filled in the UK with 900FP down, a weight of just 606g ensures the Mythic Ultra 360 provides one of the most efficient warmth-to-weight ratios in the world.
