Yahi'or (Let there be Light)

Project title

People who hike or travel frequently to explore know this better that how inconvenient it is to explore a new place when sun sets and absence of light makes it difficult. Carrying things become burden, how about carrying smart product which can multitask for you? Sounds smart itself, isn't it? An average backpacker tends to keep 20-25 products apart from general clothing. It was to figure out one of the common product carried by general population and innovate it in a most convenient and unobtrusive way possible. For example, what about a water bottle?
