Some background on outdoor winter camping
Goose down is used as a filler in winter sleeping bags and clothes for extremely cold environments. Quality goose down jacket, pants, shoes, and gloves will keep you warm at any winter temperature. In addition, layered clothing and sweat prevention is key to comfortable winter camping.
Insulation depends on the puffiness of your cover/clothing. It doesn't really matter how many layers and goose down you wear; they don't do much to insulate you against the ground. When you lay down, all the layers compress under your weight and put you in close contact with the cold ground. This makes you rapidly lose heat. This is why all the winter sleeping systems include sleeping pads.
The idea is to integrate an inflatable insulation layer into the back of your goosedown insulated pants, jacket and hood. The inflated hood serves as a pillow.
There is a miniature inflation/deflation pump in your pocket. At the click of a button it inflates the insulation layer. Voila, you are ready to sleep.
When you're ready to leave, you flip another switch and the same pump pulls the air out of your insulation layer, returning your clothes back to normal.
The jacket and pants are stretchy so that you don't feel constricted when the insulation layer is inflated.
Clothing line and designs
A clothing line could be established that sells urban stealth camping clothes. There would be various models to choose from. Anything ranging from onesies that are basically wearable sleeping bags, to stealthy looking clothes that hide their true purpose.
