ISPO Award Winner 2025: Mythic -6 by Rab

In alpine terrain, carrying less often means giving up comfort. Rab’s Mythic -6, winner of the 2025 ISPO Award, breaks that logic. At just 700 grams, it delivers true cold-weather performance through a precisely engineered design. The core: 900FP RDS-certified goose down and Rab’s patented L.O.F.T 3D baffle construction. Twisted into a helix shape, the offset baffles prevent cold spots and increase thermal efficiency—while keeping weight and volume to a minimum.

This focus on material logic runs through every detail. The Mythic -6 uses 10D Pertex Quantum for its outer shell—light yet durable—combined with recycled Atmos lining and Thermo Ionic Lining Technology (TILT) to retain heat. A PFAS-free hydrophobic down finish keeps insulation dry and lofting, even under moisture stress.

The Mythic -6 is part of a wider overhaul of Rab’s sleeping bag range. “We’ve completely reimagined our Spring/Summer 2026 sleeping bag collection from the ground up,” explains Tim Fish, Rab Product Director. “The Mythic bags showcase the pinnacle of our engineering capabilities, featuring patented L.O.F.T 3D technology that exemplifies our passion for innovation. This technology breakthrough has elevated our entire range of versatile sleeping bags.”

Beyond engineering, the Mythic -6 reflects a shift in how Rab balances performance with responsibility. All down is treated with a PFAS-free Grangers finish. The lining includes recycled materials. Packaging is redesigned: polybags with recycled content, paper-based tape, and recyclable outer cartons. And crucially, the bag is hand-filled in the UK, with production partners audited under the amfori BSCI framework and supported through Rab’s Fair Wear membership.

Ultralight, technically sharp, and transparently made—the Mythic -6 shows how Rab translates mountaineering know-how into product innovation. Its ISPO Award 2025 win marks more than a single product success; it reflects a shift in how high-performance gear is developed. By uniting patented design, recycled materials, and regional manufacturing, Rab sets a new reference point for what technical equipment can be. For specialist retailers and alpine professionals alike, the Mythic -6 isn’t just another sleeping bag—it’s a signal that function and responsibility are no longer in conflict, but advancing together.
