The Rab Mythic 400 Down Sleeping Bag (-6C) is for alpinists and mountaineers who want to save as much weight as possible on fast-and-light missions into the mountains. Every feature is made to shed grams: high-loft 900FP goose down provides high warmth at a lower weight, chevron baffles reduce the volume of the fabric needed compared to horizontal baffles, the 7D Atmos outer is ultralight yet durable to withstand abrasion, and the narrow mummy shape fits your body's natural shape to remove wasted space and weight. All in all an extremely light bag for those who favour performance for long alpine routes with a bivy stop, trekking, and the like, above all. Best for spring and autumn use.
