Recommended to all travellers

This is really great for anyone travelling abroad. Instead of buying bottled water you reduce your footprint by filtering local tap water.

Good filter

Did a good job on the trail filtering stream water last month on the Pine Mountain Trail. It's lightweight and the filter will fit my CNOC 1 liter bottles but I choose to catch the water in the bag %26 filter into my water bottles.
