Rab Mythic 400

Ultralight outer fabrics not only reduce the weight of the Mythic sleeping bag range, but also allow the exceptionally airy down to perform at its best. With 900 fill power down, heavier fabric could easily compress the insulation and reduce its effectiveness.

This Spring 2025 updated model has been designed with enhanced user comfort in mind. The zipper length has been extended from 1/4 to 3/4, making it more practical. Additionally, an internal pocket has been added for items like a headlamp or contact lenses. The bag also features a slightly increased circumference for a more spacious feel.

The back of the bag boasts fabric strips that enable you to slip a back-sleeper’s sleeping pad through.
