In order to live, you need food, shelter, and water and out of those three, in most cases, the lack of water will end your time on this planet faster than anything else. If you’re out in the woods, you can probably find water pretty easily but you can’t drink it straight. With the TrailShot Pocket-Sized Water Filter, you can drink straight from the stream.

Humans will get really sick if they try to just drink water in nature without at least boiling it first. Even if it’s clear as glass, there are tons of bacteria and protozoa floating around waiting to infect your guts and ruin your entire trip. This handy device filters out 99.9% of them.

It is actually handy, it folds up and fits in your pocket so you can pack it with wherever you go. It can fill a one liter bottle in about 60 seconds but if you don’t have a bottle you can drink directly from this tool. You can get your own for $49.95.
