Cosmic Sleeping Bag: 0F Synthetic

At the intersection of lightweight and warm, we found Kelty's Cosmic Sleeping Bag (0°F Synthetic) to give us toasty, comfy slumbers on chilly nights out in the backcountry while also packing down small to take up less room in our pack. The new insulation captures warm air and reflects our body heat back to us, so we wake up completely rejuvenated and ready to cover more trail miles.
