The Go Flow Water Gravity Bag is the ultimate filtration system that is lightweight and will go anywhere you go. The simple design enables the maximum amount of filtration, while providing a convenient and uncomplicated experience. It is compatible with the Versa Flow Ultra-filtration Hollow Fiber filter. It is also compatible with other gravity style filters.

Made from food-grade Thermoplastic Polyurethane Plastic (TPU) which is waterproof and strong. TPU’s flexibility allows for better containment and cleanability. The quick release valve is fused into the TPU preventing leaks. Located on the side of the 10 liter storage capacity water bag, the placement allows unwanted sediments to fall to the bottom of the bag and not enter into the filter. This reduced the chances of clogging the filter.

The 35 inch hose has a pre-installed quick connect that will easily connect to the quick release valve. A hose clamp only needs to be squeezed tight to slow or stop the flow of water.

With a roll-top style opening, reinforced with nylon straps creates a wide opening to easily fill the bag. Fill the bag leaving 4-5” at the top of the bag, pinch the top closed, roll the top band over itself 2-4 times, fasten the buckle across the top, connect the shoulder strap and carry it to your camping spot. In your campsite find a secure branch, disconnect one of the hook clamps, string the strap over the branch, and re-connect the hook clamp to the roll-top D-ring. Adjust the strap accordingly for the desired height.

The Go Flow is a straightforward water filtration system that is lightweight, durable, and reliable. Compatibility with the Versa Flow and shower attachment, this makes the Go Flow perfect for camping, hiking, or emergency preparedness.

    ALL of them LEAK!! PLASTIC Taste!!

    Posted by James on Sep 28th 2023

    I have been dealing with hydroblu for over a month and have received 3 bags . All of them leak. They done testing on new bags at hydroblu and said they ALL have minimal leaks. This has been a pain and can not recommend the bags. Hopefully they will get this problem resolved. I seen leaks mentioned in other reviews. I was hoping to receive a good bag. If you can get rid of the terrible plastic taste and receive a leak free bag they would be great.

    Love the bag design. Would like to see a clear version. Use case is filtering silty water. I would like to hang the bag wait for the silt to settle below the drain hole. Then filter the water. The idea is to minimize the amount of silt being trapped in the filter, preserving flow rates for longer periods.

    Great; if didn’t...

    Purchased this a year ago; tried it out for the first time last week. It worked great at filtering the water. But on the second filling of the bag, it developed a pinhole leak. Glad I didn’t need to hike with the bag this week.

    Went hiking and camped over night with a couple friends. The bag seems pretty durable and it was nice we could just throw it in the car and go. The strap didnt really bug me which was nice.
