Doppelganger Sleeping Bag

There’s no shortage of multi-purpose and multi-functional tools and clothing in the market. The latest one is called the Doppelganger Outdoors Wearable Sleeping Bag that’s currently being sold on Japan Trend Shop. As the image above implies, the Doppelganger is a jacket, a coat, and a sleeping bag, all rolled into one nifty but silly-looking package.

Strange appearance aside, it’s perfect for when you’re planning to spend some time in the great outdoors. The purple part is the jacket, which you can wear for some extra warmth or protection from the elements. Unzip the bottom part and the gray part of the jacket provides some extra leg protection. When you’re ready to go to bed, just extend the blue part and voila!–it’s now a sleeping bag.

The Doppelganger Outdoors Wearable Sleeping Bag retails for $138.
