Duranor™ Camping Sleeping Bags

Stay warm without packing a brick.

The Naturehike Snowbird is a mummy-style duck down sleeping bag built for backpacking and cold nights. Soft 650FP down traps heat, the water-repellent shell helps shrug off light moisture, and the bag compresses into a small stuff sack for the trail.
