If you’re going to venture out into the wilderness, it’s always a good idea to have backup plans in case your infallible sense of direction ends up failing miserably. What do you do if you’re stuck out there for a few days with nothing but muddy water all around to keep you hydrated? The NDūR Survival Straw is an inexpensive product that can go a long way to keep you alive. Featuring a fairly sophisticated water filtration technology from Seychelle, the straw claims to “eliminate up to 99.9 percent of micro-organisms, up to 99.99 percent of all chemicals and heavy metals, and up to 99.9999 percent of viruses and bacteria.” All you have to do is dip the straw in the stream, and drink away. It’s able to treat up to 25 gallons (95 l) of water before needing replacement. Best of all, it’s only $30. That’s a perfect pricepoint for anyone to consider making this a permanent member of their outdoors survival kits.
