Overview: This is a great new bag from Sierra Designs called the Mobile Mummy Sleeping Bag. As you can see from the images and video, you can pop your legs out of the bottom of the bag, so it’s great for relaxing at camp and staying warm without wearing your jacket. If you have to go to the bathroom in the middle of the night you don’t have to take your sleeping bag off. This bag has been getting a lot of really positive feedback for winter camping.
