Go Flow Water Gravity bag construction...
The HydroBlyu filter products are well thought out and I really appreciate the versatility of the filtering options. That said, the gravity flow bag construction needs some tweaking. The first bag I purchased leaked on the first use with less than 30 liters filtered. Luckily the versatility of of the system saved us as we were able to adjust while in the backwoods. HydroBlu stood behind their product and once I showed them the failure, they immediately send me another kit, although I onl9y needed a new bag. Th problem was with the bond between the bag's vinyl coated fabric and the plastic of the hose valve body. That heat weld does not hold up to the weight of the water when you carry the bag. I don't know the exact moment the bag failed while camping so I was interested in examining the replacement that HydroBlu sent me. When the bag arrived I immediately unpacked it and reviewed the construction at the valve body. I gave it a moderate tug approximating the weight of 10 liters of water and this seam popped right open. This really should not happen and I think that this problem needs to be addressed so folks are not stranded without water options in the back woods. Again ,HydroBlu was responsive to my first request for product replacement. I am not sure I want to request another.

BWCA water filtration, shower.
While in the BWCA , my daughter and I utilized the Go Flow Water Gravity Bag, Versa Flow with Activated Carbon Filter and the Clear Flow Water Bottle and Filter Combo with great success. We used one water bag exclusively for filling with, "dirty" water. The other two were for the clean filtered water. That way we always had one full filtered bag while the other was filling. We also used one full bag for showering. I simply drained out half, heated it, then poured it back in for a hot refreshing shower. The Clear Flow Water bottle worked great while on the water away from camp by simply dipping it full and drinking. This alleviated the necessity for carring extra prefiltered water bottles. Knowing I have the necessary equipment and knowledge to purify water in any situation, I'm at rest having a plan for whatever is thrown my way. I did have to sleep wirh the Versa flow filter when the temp got down to 25°F to keep it from freezing one night. Backflushed the filter a couple of times to regain the flow rate. Don't forget to bring the backflush bottle. Have been using their products for many years and will continue to do so for years to come. It is cheap health and safety insurance.

Exactly what I was looking for!
This was recommended recently at a preparedness workshop I went to. I wish I would have had this system over the past many years! As a camper, hunter, backpacker and overseeing teens backpacking, this would have been well used. I may buy it for all my grown children.

Love this filter!
Took it backpacking with a few people and it was so much quicker than the mini “squeeze bag” filters out there.

good...
works great

System works...
I have been using the Go Flow Water Gravity system for the last 3 years, this purchase is for a backup as the original is 3 years old at this point. It works efficiently and reliably.

Absolutely...
I love this thing, it holds 10 liters of nasty water, slap on the filter and it comes out clean as can be, it's great so you don't have to carry as much water with you which is vital sometimes.
