Learn MoreThe Perform Down Sleeping Bag is an easy choice because it acts as our nighttime coverup in the backcountry, whether it's December or July. That's because, aside from the super soft and lofty down fibers keeping us warm, Mammut designed their own specialized mummy shape to keep in the heat. They also moved the zipper from the side to the top to better regulate temps when snuggling up in the bivvy or tent.
