Solo use on the hike, whether you're just out for the day or multiple days on the trail, just find your source and start pumping. It provides 3L of water per minute and includes a Quick Connect bottle adaptor so you can send it directly to your drinking vessel.

Rated 2 out of 5 by from Find another solution I have used this section hiking on the AT and performance was ok, but despite backwashing water filtration became a major chore. We used it last year on a 10 day trip in the boundary waters and performance was awful. We used two new cartridges over the course of the trip and ended up boiling water to be safe.......and this is in the boundary waters where the water is pretty pristine. Very disappointing. I am on this website looking for a better solution.

Rated 2 out of 5 by from I would read reviews at least a year old. This product is good off the shelf and so light for a fast filter. BUT, the combined issues of: - Not working well on backflow flushes - Needing Lubricant (Not included) - Having hard to find valve parts - Having fragile valves (Especially the small orange one) - Being unable to allow to freeze, Make it a bit too much hassle, which is too bad because when it's brand new it rockets clean water. If they can include lube and spare valves the troubles would be much less.

Rated 5 out of 5 by from Awesome! Lightweight & Quick I was surprised about how quick the pump was able to fill my Nalgine. It has great interchangeable ways to attach the pump to various containers.

Rated 4 out of 5 by from Reliable filter for backcountry excursions I have used it on a regular basis in and around So California - hunting, hiking, backpacking, etc. I use it mostly as a group filter as for solo trip I use a smaller filter. I've had none of the problems that some others have listed. I have back flushed the filter at home a few times for the heck of it. It continues to filter water quickly with minimal effort. The pre filter has a velcro strap to hold a rock or such. This holds the pre filter at the bottom of the creek or wherever you place it. My only complaint is that mine weighs more than the listed weight on this website, only a couple of oz difference but it adds up.

Rated 5 out of 5 by from Fastest System Yet I have used this filter about 10 times now and It has not shown any sign off clogging; its fast and fills a 32oz nalgene (adapter cap included) in 20 strokes. It also attaches to a MSR Dromedary Bag, so you can have reserve water if needed (we always use every bit of pumped water for hanging out at the campfire and early morning cooking and refills for the next days hike). We have had several MSR water filters, stoves, etc... Always quality mountaineering products.

Rated 5 out of 5 by from This is finally my solution I am using this, with a bit of jiggering, to fill my Osprey 3L bladder while it is in my pack

Rated 5 out of 5 by from Great Basic Filtration System Used for multi day backpacking trips. Straight forward, easy to use, basic filtration. Use mainly for one or two people because it is manual vs gravity, so does take some time- nothing out of the ordinary.
