Tyler Rudolphwrote a review of Katadyn Gravity Camp 6L Water Filter on September 20, 2015
Familiarity: I've used it once or twice and have initial impressions
I used this today on a day hike to test it out and it worked like a charm. I filled it up on a river bed and used some paracord to tie it to a tree. I wish the bag it came with was a little more waterproof. I will just pack it in a ziplock next time. Also, doesn't come with paracord. The fill line is a little long, so after my hike I chopped mine in half. I didn't want the nozzle to scrape the ground. I can say it took some dark river water and filtered the sand out and gave me some quality H2O!
