Waterdrop Gravity Water Bag, Compatible Water Filter Straw, 1.5 Gallon

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.

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.

Gravity Filter bag works as expected

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.

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!
