Rab Sleeping Bag, left opening Mythic 600

Weighing just 925 g, it contains 600 g of goose down with a fill power of 900 cuin. The chevron baffle construction keeps the down in place, optimizes warmth around the torso, and reduces the amount of fabric needed compared to traditional horizontal baffles. The exterior is made from our own recycled Atmos™ fabric, which is water and wind resistant. The narrow mummy shape of the sleeping bag makes it very packable, and the zips and pull tabs are very lightweight. It packs down into a lightweight, waterproof compression sack with a roll-top closure for optimal weather protection and minimal bulk.

The trapezoidal baffle design allows the down to stay well lofted to eliminate cold spots and optimize warmth. It features an adjustable neck baffle and an internal baffle along the zip, both designed to prevent heat from escaping. Hand-filled in the UK, all our sleeping bags have the advantage of not having their down compressed before use, thus retaining their warmth and loft.
