Product Info

The Rab® Mythic 400 Sleeping Bag is Rab's top of the line backpacking bag. It's ultralight, has a versatile 3-season warmth rating, and packs down to a tiny size. Only the finest 900-fill hydrophobic down is selected for these bags, and a unique baffling system holds it all in place to avoid cold spots. Weight has been trimmed wherever possible, but comfort is never sacrificed, as evidenced by the careful balancing of tapered lines, an angled footbox, ultralight trims, and internal collaring. This is the sleep system of choice for big wall climbers, long distance through hikers, and anyone else who absolutely needs the best performance and lowest weight for a wide range of conditions.
