A wearable standing sleeping bag like this is designed to improve your camping experiences. The concept and design are based on years of input from ordinary campers who have stated over and over again what a drag it is to have to leave the comfort of the sleeping bag behind to make a trip to the outhouse or to sit around the fire in the evening and enjoy a cup of tea. At the end of the day, it's all about versatility so the wearable sleeping bag is a part coat, part sleeping bag. It's never going to be as good at either of those things as a dedicated sleeping bag or insulated jacket. But it does a good job of being a unique piece of gear that will drastically improve your life if you're always cold.
