Burtrail Gravity Water Bag, 3L Water Bag Compatible with Water Filtration System, Portable Gravity-Fed Water Bag for Camping Hiking Backpacking, Foldable & Hangable

I was going to get a Cnoc bag, having had one in the past, but opted for this one instead. Really pleased with the durability and usability of the product. Not only is the bag on par with name brands but the addition of a tube/ hose, a hose clamp, the extra line to hang the bag, and a quick release port really set this one above and beyond.It also is a direct fit for Sawyer products. Outstanding!

Product will serve the purpose I bought it for just fine.

This is a great universal gravity filter bag. It's definitely one of the best gravity bags I've ever came across. It should work just fine with any of the common filter systems out there. I am currently using it with my Aquasiv filter, which it works great with. It's a nice large gravity bag and holds 3 liters. Which is a lot of water. You can pretty much process a whole day's worth of water in one go with it. It's very well made, quite durable, and can handle squeezing if you're in a hurry. It's also pretty lightweight for its large size. The bag and hose together only weigh 165g/5.8oz. The hose is a quick connect, which I really like and makes it much easier to pack up. It has a large reinforced opening that is very easy to hold open by just squeezing the sides. It's a great way to process a lot of water when you're just hanging out in camp or taking a long break. It's a great addition to any filter kit. I'm very glad I now have it as part of mine and I would recommend it.

Received this item and was so excited to use in on my next backpacking trip. I tested it at home as you should anything before trusting it when backpacking. Seemed to work really good. It was going to be nice just being able to fill it up and just let it hang there unattended while it made my water. All was good till I accidentally threw it in the fire. smh. I'll by another one.

This gravity water bag is perfect for outdoor trips. It’s easy to fill thanks to the wide-mouth design, and the material feels sturdy and durable. I love that it’s compatible with my existing water filter and turns it into a gravity-fed system. The suspension system is a smart addition, making it convenient to use at camp. It hasn’t leaked, even under pressure, and the hose and regulator work smoothly. Definitely a reliable option for safe drinking water outdoors.

This gravity filter kit is composed of three parts: the "dirty" water bag which you use to scoop up water, the cord and clip you use to hang it from a tree branch or such, and the connecting hose which goes between the bag and your filter and includes a clip-type flow control valve.The bag is very convenient and easy to fill, as the mouth opens very easily and wide when you slide off the blue handle. The handle is made of strong but light plastic and is perfect for holding up the approximate 6 pounds/3 kg of water when it is full. The cord is also light and strong and the included carabiner lets you just throw it over an overhanging branch or around a tree trunk and clip the bag to it. Very easy.The included plastic hose is very tough and allows you to see the water flowing through it, it connects to a Sawyer filter, Lifestraw or most other filters of this type as you can see in one of my pictures where I am using it with my filter. The filter is not included.This kit is very lightweight and increases the utility of your mini filter greatly as you no longer have to squeeze anything or carry a pump type filter. You just hang it and let gravity help you fill up to 3 one-liter water bottles.

This is the kind of hydration bladder that I prefer - a top that completely opens so that it is quick and easy to clean and dry out. I've got a couple of these in 2 liter sizes, but this is the first one I've gotten in a 3 liter size, which I need for those hot summer hikes in the mountains.I already have a bag for my gravity filter setup, but this comes with all the accessories I'd need if I was just starting out. The pinch clip might seem like a small thing, but it's really handy. Mine doesn't have a rope, just a loop of webbing and something this doesn't work well so I'm going to be using the rope and carabiner with my normal kit.I filled the bladder up to test it for leaks and it had no problems.The instructions aren't kidding when they say it'll be hard to open the first time. I'm glad they mention that because I didn't even look at them before I tried to open it and then came back to the instructions to make sure I wasn't missing a secret catch or lock somewhere. Nope, it just requires so much force that I had to get the pot grippers out to get a secure hold on it. Other than that, no problems with this.

This is a useful water bag. It would be really useful if it came with just one of the many filters it claims to work with. I'll do a better review of the bag after I find and buy a filter. This is like buying shoes and being told the shoes will work well with the shoe strings of your choice, bought separately.
