(If I need to carry water, I can always use my pot to finish filling the 2-liter Dirty bag all the way.)


Instead of filling the container directly, I use a ziploc bag. I put my filter inside a quart size ziploc for storage. I fill up the ziploc from the stream, then pour that into the container. The ziploc fills instantly, even from a shallow water source.
