This is a concept that uses different elasticities to create drumming sounds from rain drops. so when you are walking around in the rain you suddenly feel like your jamming or at a rock concert. I think the problem with this umbrella is that you can’t fold it, otherwise you would mess up the sounds and also it has a very irregular shape so while your head might stay dry your back probably wont. If this does ever hit the market I would totally buy one just to take to Vietnam and see how epic of an solo the monsoon season can bring.
