Rab

Ultra-lightweight with a highly tapered cut, the Rab Mythic 600 is designed for alpine-style missions where weight and pack size are crucial to success. Filled with 900FP goose down and covered with a lightweight recycled Atmos™ fabric, it's a high-performance bag for those meticulously counting grams.

The Mythic range is all about slashing weight wherever possible. The Mythic 600 is an extremely lightweight four-season bag. At home in high mountains, it’s ideal for venturing out on long alpine routes, multi-day climbs, treks, or bikepacking adventures.

Weighing in at just 925g, it contains 600g of 900FP goose down. The chevron-style baffle design keeps the down in position, optimizing core warmth and reducing the amount of fabric needed compared to traditional horizontal baffles. The outer is made from Rab's own wind- and water-resistant recycled Atmos™ fabric. The bag has a narrow mummy shape to minimize bulk, lightweight zips and pulls, and comes with a lightweight, waterproof, roll-top compression sack for protection from the elements and a small pack size while on the move.

The trapezoid boxwall baffle construction allows the down to fully loft, eliminates cold spots, and maximizes warmth. It has an additional, adjustable baffle around the neck and an internal baffle along the length of the zip, both designed to stop heat from escaping.

Hand-filled in the UK, all of Rab's down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
