Best Out There
This unit has been around for decades and still works as described. I had one some 20 years ago and it is pretty much fool proof and intuitive to use. As an added advantage with a quick connect added to the outlet side it will plug into a number of drinking tubes on your hydration bladder or if yours is not already equipped with quick connects you can buy the fittings for a few dollars. That means no taking the bladder out of the pack and trying to stuff it back in. That also means that the water that goes into your bladder is filtered as opposed to filling the bladder with dirty water and then filtering at the drinking tube end like some systems. All and all a much better system with fewer moving parts to go wrong. Not cheap but you will never regret buying it and it has enough capacity to handle your needs and multiple friends. Pumping rate is about a liter per minute so in a couple of minutes most bladders are filled. The gold standard in filters.
