Shurex Gravity-Fed Water Bag for Sawyer Survival Water Filter Straw, 1.5 Gal Large Gravity Water Bladder Compatible with LifeStraw and Other Water Filter Straw, Foldable, BPA-Free (6L)

Works great! Just hook up a sawyer filter and go! It's made in China, so I'm not 100% confident in the materials. I recommend filtering through the bag within an hour or so - I've noticed a bit of plastic taste if left for an hour with the clip on. No big deal as I always camp next to water.

I can't figure out how to make this work. I connected the tubing to the bag by pressing in the gray button and pushing the connection up inside. As long as I hold the connect or pressed against the top inside water will flow if I let go nothing happens.So - the little button is a slider thing , looks like you have to slide it back to the forward position to lock I in place.Now it's working! And works great, effortlessly just find a place to hang the bag. At my cabin location, I cut a little hole for the tubing in the lid of a gallon water container and processes and fills easily! I simply use a "dirty water fill gallon" and let the bag - with a Sawyer Mini attached - stay near the outdoor sink.Great - I recommend!

The water filter system works well. Like its design. But a issue is that the rings at the top of the water bag, which you are supposed to attach to the hooks of the strap, the size of these rings are wayyy too small.When you are carrying a 6kg load and trying to attach it to a tree branch, you don't have the energy to play around with hooking on such a small ring.I am going to buy some carabiners separately, to make it easier on myself

Wide opening to fill water. The water flows when hose is clipped on. The plastic close-off-clip on the hose is so so. I rather just super elevate the hose end above the bag. Robust bag and hangs easily. I used it with a Sawyer squeeze. The hose end is marginally loose to the Sawyer screw-on kit. A tight rubber band worked for me to stop water dropplets between hose end and Sawyer screw-on

I really liked this water purification bag, with the line attachment being on the side, allows for any settlement that gets picked up to settle on the bottom and not to go through the filter. The hose, the clamp, the bag and the straps all worked very well. The only thing is that it doesn’t come with a second hose so once you add the water purification filter (bought separately) another hose is not necessary, but works well in order to fill up bottles containers, pots, bowls, and whatever else that you need the water for. I definitely found it affordable, functional and would highly recommend it for any back country camping. Or any place requiring clean water. 👍😁
