Rab Mythic 400 Sleeping Bag Left Zip cloud

The Mythic models are all about keeping weight to a minimum. The Mythic 400 is an extremely lightweight 3-season sleeping bag. This sleeping bag belongs in the high mountains and is ideal for long alpine routes, multi-day climbing tours, trekking tours or bikepacking adventures.

The sleeping bag weighs only 660 g and contains 400 g of 900 cuin goose down. The herringbone chamber design stabilizes the down, optimizes body heat and requires less material than traditional horizontal chambers. The face fabric is made from our proprietary wind and water resistant Atmos material. At only 7D with integrated ripstop, the sleeping bag is ultra-lightweight and super durable. It has a slim mummy shape, hardly any bulk, lightweight zippers and zipper pulls. It comes with a lightweight, waterproof compression sack with roll-top opening for protection from the elements and compresses to a small pack size when on the go.

The trapezoidal boxwall chamber construction means that the down can puff out completely. This means cold bridges have virtually no chance, and warmth is maximized. It also has a width-adjustable thermal collar and a windbreak chamber inside along the zipper, both of which serve to prevent heat from escaping to the outside. All our down sleeping bags are filled by hand in the UK; the down is basically not compressed before use, so its bulking power and warmth of the down is preserved.
