Rab Mythic -6C / 20F
The Rab Mythic (-6°C) is an ultralight, high-performance sleeping bag engineered for fast-moving alpine missions and technical mountain terrain. Designed with a relentless focus on reducing weight and bulk, it delivers exceptional warmth-for-weight performance for climbers, fastpackers, and alpinists operating in cold, demanding environments.
Filled with premium 900 fill power down, the Mythic uses advanced L.O.F.T 3D™ helix-shaped baffle construction to eliminate cold spots and maintain even down distribution. This innovative structure creates internal funnel points that prevent down migration, ensuring consistent insulation throughout the bag while minimising weight and packed volume.
A key feature is the integrated TILT (Thermo Ionic Lining Technology), which reflects radiant body heat back towards the sleeper, significantly improving thermal efficiency without adding bulk. The outer shell is made from lightweight Pertex® Quantum ripstop fabric, offering durability and wind resistance for alpine conditions. Hand-filled in the UK, the down is never pre-compressed, preserving maximum loft and long-term insulating performance. Built for serious performance in cool alpine conditions, the Mythic stands at the top end of ultralight sleeping bag design.
FEATURES:
- Pioneering L.O.F.T 3D™ construction features helix-shaped baffles that prevent down migration and maximise warmth retention.
- Built with a heat-reflective TILT lining, minimising radiant heat loss for virtually no extra weight.
- Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.
- Cinch in the hood to seal in the heat, while the down-filled collar sits snugly around your neck.
- The tapered mummy shape is incredibly efficient on pack size.
- ½ length zip features an insulated zip baffle to prevent cold spots when the temperature drops.
- Internal cordlocks positioned below your collar bone for greater side sleeping comfort.
- Anatomically shaped foot box allows you to sleep in a relaxed position.
- Lightweight dry bag compression stuff sack.
- Zipped storage sack with water-resistant base for home storage.
- Hand-filled in Derbyshire UK.
