>>1743946I'm using a bit of an odd system. I bought an MSR 4 gallon biodrome years ago. Then I bought an MSR drink kit like 2 years ago. I had bought a Sawyer Mini with the squeeze bag with all this. Well the squeeze bag finally up and died so I went and started looking for a new setup. My buddy had an inline system that I was really jealous of, so I bought the Sawyer inline adapter. Now I wanted something to replace the squeeze bag. I really liked my buddies setup so I went ahead and copied that which required me finding another drink bag and setting that up as a gravity filter with my sawyer. The end result is this wacky setup you see. I bought a $10 drink pouch off Amazon that holds 2L and I remove it's drink nozzle and attach it to my sawyer mini. The mini then attaches to my inline and BOOM gravity assist filtered water filling into my pack. It's a pretty good setup and you can duplicate mine for even cheaper.
Buy 2x of these -

Then assemble it into a dirty water pouch/filter to a pouch/drink/fast fill setup. Now you can fill your water bag without ever having to remove it from your bag. You also have a modular filter system that isn't propritary and can connect to any 1/4" hose.
