Rab Mythic 0C / 32F

The Rab Mythic 0C represents the pinnacle of ultralight sleep systems. Engineered for fast-and-light mountain missions, mountain marathons, and bike-packing, this bag offers one of the highest warmth-to-weight ratios in the Rab range. By combining 900 fill power down with cutting-edge TILT technology, Rab has created a sleeping bag that defies its 500g weight.

The secret to the Mythic 0C's performance lies in its construction. It features TILT (Thermo Ionic Lining Technology), a heat-reflective coating that significantly reduces radiant heat loss without compromising breathability or pack size. This is paired with L.O.F.T 3D baffle technology, which utilizes advanced internal architecture to eliminate cold spots and ensure the down remains perfectly lofted over your body.

To achieve its ultralight status, the Mythic uses a 10D Pertex Quantum outer. This fabric is incredibly thin yet remarkably durable, allowing the 900FP European Goose Down to reach its maximum loft. The down itself is treated with a Grangers fluorocarbon-free hydrophobic finish, ensuring it maintains its thermal properties even in the damp conditions often found in high-alpine bivys or condensation-heavy tents. The tapered mummy shape is meticulously designed to minimize "dead air" space, while the anatomically shaped foot box allows for a natural sleeping posture. To further shave grams, the bag features a weight-saving 1/8 length YKK zip with a dedicated down-filled baffle. Every Mythic 0C is hand-filled in Derbyshire, UK, ensuring the down is never compressed before it reaches your door.
