This umbrella may make you feel like you are living on your own planet, but it seems guaranteed to keep you dry even in a gusty downpour. It also collapses into an unobtrusive shape. My question is: can you put it up and on in a hurry ?
Jake Gyllenhaal made it cool to live in a bubble in "Bubble Boy", and Nubrella is making it luxurious. Made of "state of the art clear thermoplastic polyurethane" (read: warm saran wrap), this spring-loaded gadget is designed to keep you warm, dry, and seriously conspicuous. ($60 from nubrella.com)
Very interesting little umbrella, if I do say so myself. It would definitely keep you dry!
