There’s nothing like a drink of water after a long hike on a hot summery day. So cooling and so refreshing and especially satisfying on longer hikes. But what happens when the water runs out? Well, naked filter water bottles is hoping you’ll untap the water sources from lakes, rivers, streams, etc.. and make it readily available to you for drinking. This is made Liquidity Nanotech, an Alameda based company, which allows you to take water from any source. So, does that mean that after you take a plunge in the lake, you can drink it afterwards? Sure does sound like it! Fresh water – anywhere you go. Now, that sounds refreshing.
