Sturdy and convenient
This this works great. I think it's a bit big for longer distances but I did pack it into a back country base camp in the dunes on lake Michigan, in April. I didn't want to go up and down the dunes for water all the time... They're brutal.... And the wide opening made this a fast fill in Lake Michigan when I had to wade out into the really cold water to avoid a bag full of sand. For a solo, I could fill this once or twice a day and have plenty of water for cooking and drinking and hygiene/dishes. It's really sturdy flexible material and it worked great with the sawyer squeeze.... You need an adapter for the hose end to the filter but they come with the sawyer system. It actually filtered really fast....I just used a lightweight bungee to secure it to the tree instead of packing that big strap. The plastic clip to pinch off the water supply is really stiff at first but it loosens up and I don't think it's awesome in quality but not a deal breaker. I would definitely like to find one slightly smaller if they make them for longer distance trips but for two or more people on trail this would be awesome as well.

Excellent gravity water filter bag!
Have used this on several backpacking trips now in line with sawyer mini. Works great! Can carry enough water to camp for the whole day (1 person) lightweight, tough construction I don't feel like im going to accidentally break it in the woods. Quick connect is great. Just open top, scoop water , roll and clip closed, attach filter hose...and filter water. Perfect gravity bag for camping/ backpacking. Buy it, you will be happy.

Good quality gravity bag, eventually failed.
Good quality gravity water bag. Easy to use with Sawyer SP128 Mini inline filters. Purchased in 2022. After eight, week-long backcountry camping trips over the last three years, the spring closure that keeps water from flowing out the bottom of the bag (when the hose is not connected) failed in 2025. No other issues during that time.

Great Quality & to have in case of Emergency
I bought this in case SHTF as a prepper, and would add on my water filter to the tube to dispense water into a food grade bucket wuth dispenser. Also good for fresh water for camping. Can use it for cleaning dishes, hands, drinking etc while camping. The only CONS, they should include a cleaning kit with brush, and the tube is not that flexible. It's a hard tube. Hopefully it will last. I don't know the inner dimension to buy extra tubing. The bag is nice. It's velvety on the outside. Nice silicone bag. Seems strong. I have not used it yet. Keeping it in my BUGOUT BAG. Allows you to hike light so u don't need to carry around full bottles of water. Just make sure you have a water filter to attach. I recciment "membrane solutions" water filter over any other brand. I tested the filter. It fits perfect with this tube included. This is great for filling and keeping on your kayak or boat too!

Great bag when you need volume.
Purchased after my wide mouth bladder sprung a leak. Took immediately on a 3 day backpacking trip to Linville Gorge with my sons scout troop. Wide opening makes retrieving water really easy. Bag is sturdy and durable. Great bladder when you need to filter for the family or a small group. Only negative I see is the roll top does not seal allowing you to carry additional water. I solved this by filtering into a 3 liter bladder. I knew the top was a roll closure and did not seal when I purchased so I had planned accordingly.

Great for scout backpacking trips
I bought this for a beginning scout backpacking trip I was teaching. It's a sturdy bag and it comes with a carrying strap as well as tubing. This was a pleasant surprise. The tubing fit my Sawyer mini perfectly. The carrying strap worked well for the younger scouts who would otherwise have trouble carrying a full bladder. The scouts had no trouble filling this bladder at a nearby lake and hiking it back to camp. We also used it in shallower water, but they didn't do too good of a job avoiding sediment, which clogged the valve at the bottom. A good teaching moment This is a GREAT, SUPER AFFORDABLE gravity filter set up. Just add a Sawyer mini and you are good to go. Absolutely no leaks. I am now recommending this to all our scout families.
