Can I use it in the backcountry?

Yes, you can use your LARQ Bottle PureVis 2 in the backcountry! First, take out the Filter Straw and fill with water that is clear to the eyes with no sediments. Then, use PureVis™ Adventure Mode (double-click) on its own. After the PureVis™ cycle is complete, put the Filter Straw back in.

As a rule of thumb in the backcountry or on hikes, stick to running water sources such as rivers, streams, or waterfalls, further away from vegetation.
