I ordered one of thes. But have not tried it yet.
I've got a Sawyer inline filter hooked up to a Platy Big Zip 2.0 and it works like a champ. You can use it as a gravity setup in camp or pop the bite valve back on the end of the line and put the untreated water right in your pack and filter on the go.
The only issue is I still need to find a charcoal pre-filter. I had one bad experience with pond water. I didn't get sick at all, but the Sawyer by itself doesn't do much to improve the taste.
