Here's an interesting design by Matthew Gales... the Excubo Jacket. It's a jacket designed for sleeping in public transportation.

"During reasearch I learned that people can sleep when their bodies are held in a rigid state as opposed to only a soft and yielding state - similar to most beds. I applied this concept to the Excubo jacket - a jacket that transforms into a firm and protective shell around the user."

And you know what that means for budget travelers? Once they start manufacturing the Excubo jacket, you will be able to save a lot of money! With an Excubo Jacket, you can now also sleep comfortably -- for FREE -- in airports!
