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 our groundbreaking L.O.F.T 3D™ construction. This unique technology uses twisted, helix-shaped baffles to create funnel points within the bag, which prevent down from migrating and keep it evenly distributed. Combined with a TILT lining that reflects heat back towards your body, this allows us to achieve an unrivalled warmth-to-weight ratio. Light on grams but not on functionality, the Mythic is finished with a Pertex® Quantum ripstop fabric to ensure it stands up to mountain environments. Ultralight, stripped-back, and uncompromisingly warm, it’s ideal for moving fast in cold conditions, from fastpacking to alpinism.
Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving its loft and warmth.
- 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.
