Walking Sleeping Bag

The Selk Bag, aka a sleeping bag you can wear around like a marshmallow suit and go exploring in... while I think this is a very cool idea and if I had the extra money to spend on miscellaneous and frivolous things I would probably be the person to invest in this, I do have to wonder why the hell I would be walking around exploring the woods if I planned on getting in a sleeping bag. I thought the idea of a sleeping bag was based on the decision to go actually go to sleep. And if it's cold and I wanted to explore the woods, I'd probably just put on winter clothes... however, it does seem extremely convenient if you need to go to the bathroom in the middle of the frigid night!
