Staff Pick!
"This product has made water filtering on long trips so much easier. The bag is super easy to fill up in rivers, streams, or lakes, and it comes with easy attachments to hang this on a tree, your trekking poles, or even a friend! I have used these on extensive trips where we had to worry about ash, sediment, or bad bacteria in our drinking water and this filter lasted through it all! If using this for a trip longer than 3 days, I recommend purchasing a plastic syringe to backflush your filter, keeping it working efficiently." - Audrey
