Rab Mythic Ultra Down Sleeping Bag (Long)

Every detail of the Mythic has been designed to reduce weight and bulk, drawing on over 40 years of hard-won expertise. It's filled with high-quality 900FP down, which offers superb warmth for its weight, in Rab's ground breaking L.O.F.T 3D construction.

For top-tier warmth and comfort, the Mythic Ultra Down sleeping bag from Rab contains technological features to offer a lightweight and easy-to-transport bag, perfect for rough sleeps. Crafted from Pertex Quantum fabric, the Mythic Ultra is lightweight, windproof, water-resistant and highly breathable for exceptional thermoregulation. This soft material also encourages insulation to fully loft for excellent thermal efficiency. With 900 fill power (FP) goose down, the insulation within the bag offers superb warmth for what it weighs, hand-filled in the UK to ensure the down is not compressed before reaching you and is topped with Grangers hydrophobic finish to prevent water from soaking in. To maintain comfort throughout the night, Rab's L.O.F.T. 3D construction has been implemented, creating offset baffle walls that twist into a helix shape to create funnel points that prevent down from migrating. On the inside of the sleeping bag, Thermo Ionic Lining Technology (TILT) can be found; this radical heat-retaining technology works like an emergency blanket, reflecting heat back onto your body all the while maintaining breathability and comfort. TILT boosts thermal efficiency, keeping you warm when temperatures drop below 0.

The Mythic Ultra Down features a tapered mummy shape, optimising weight while ensuring adequate comfort. This design extends to the anatomically shaped footbox as well. The side baffles enable side sleeping, reducing any cold spots and preventing you from lying on seams. Additionally, the cinch hood helps seal in the heat with a down-filled collar that sits snugly against your neck. The hood can be cinched tight by toggling the cord locks found on the inside of the bag, positioned below the collarbone for side-sleeper comfort. A half zip has also been implemented into the design, with an insulated baffle for preventing cold spots. When transporting the bag between camps, simply stuff it into the lightweight dry bag for ultra-compact carrying. For storage in-between adventures, place the bag in the large zip storage sack, which features a water-resistant base designed to help maintain the loft of the down over extended periods.
