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 highly packable, it’s ideal for your fast-moving spring missions.
Our Mythic sleeping bags redefine warmth for weight, meticulously shaving grams and minimising pack size to bring you performance without penalty.
