What is the Mythic Ultra 360?
Rab's game-changing Mythic Ultra 360 sleeping bag has been updated with a new recycled face fabric and lining. Featuring the same premium 900 FP down and innovative TILT technology, this ultra-techy sleeping bag is aimed at fast and light adventurers counting every gram.
What is it made from?
Insulation: The Mythic Ultra 360 uses 360g of 900 fill power, R.D.S Certified, European Goose Down or maximum loft (fluffiness) and insulation.
European Goose Down is some of the highest quality down on the current market, making this sleeping bag super high grade and efficient for keeping the heat in. The bag is also hand-filled in the UK to ensure the down has not been compressed before use to retain its loft for your first epic adventure.
The down is treated with a Nikwax fluorocarbon-free Hydrophobic finish, which adds light water resistance to the down itself.
Can't quite catch the lingo? Here's a quick breakdown.
Fill power - Fill power measures the warmth and efficiency of the down, alongside its ability to loft (fluff up). A rating of 900 fill power means that 1oz of this down fills 900 cubic inches of space when fully lofted.
R.D.S - The Responsible Down Standard ensures that the down is sourced from happy birds who haven't been plucked and have been well cared for.
Hydrophobic - Hydrophobic down dries out and lofts more quickly than untreated down, resisting moisture from sweat and condensation that may build up when you're catching z's in the bag. Fluorocarbon-free Hydrophobic finishes don't use harmful chemicals that cause damage to the environment, an excellent feature for more eco-conscious adventurers.
Lining: The lining uses a 10D recycled Atmos™ fabric with thermo ionic lining technology or TILT for short. This clever technology utilises titanium-coated nylon fibres to create an almost 'foil blanket' effect whereby your natural body heat is reflected back to you, increasing warmth by 32% without adding a gram of weight. And no, it doesn't feel like a foil blanket, it feels exactly the same as a normal sleeping bag fabric! Neat, Right?
Outer fabric: The outer shell of this sleeping bag is made from the same 10D Recycled Atmos™ fabric, minus the TILT technology. Recycled Atmos™ is made from super-fine, tightly woven yarns, making it windproof, fast-drying and highly water-resistant to protect you from the weather on mountain adventures.
This fabric is treated with a fluorocarbon-free, durable water repellent (DWR) for extra weather resistance in slightly harsher conditions. It's also super handy for accidental drink spills or getting caught out in sudden showers when setting your kit up. Fluorocarbon-free finishes don't use harmful chemicals that cause damage to the environment, which is another bonus feature for those seeking a more sustainable sleeping bag.
What are its features?
The Mythic Ultra isn't loaded with features, as it's designed to be as light and packable as possible, but it does have some performance-boosting additions. There's an internal insulated collar within the hood designed to trap heat, an angled foot box to prevent your feet from squashing down and reducing its efficacy and a weight-reducing 1/8 length zip with a glow-in-the-dark zip pull. Even the included compression sack is made from lightweight materials!
The overall shape of the bag is a tapered mummy shape to provide efficient coverage to the whole body. A trapezoidal boxwall construction directs more insulation towards the body's surface by forcing the down to sit in a trapezoid shape within each baffle. This construction method optimises the loft and warmth of the bag. The chevron shaped baffle design helps reduce migration of the down, whilst optimising core warmth, by encouraging the down to sit in the central points of the sleeping bag.
