Large opening water bag can also be called full opening water bag. It is a new high-quality water bag designed to solve the problem of poor cleaning and maintenance of water bags!

Generally speaking, when hiking, even if there is no water supply halfway, the water bag filled with 2-3l water is enough for a day's hiking. The following are considerations:

1. Capacity: however, under the extreme conditions of muggy heat, sweating and rapid water loss, we once thought it was not enough to drink 6L of water a day. In addition, we need to draw water for cooking, boil soup and make tea after camping. When the camp is some distance from the water source, in order to avoid energy consumption, waste of time or unsafe factors caused by one person drawing water, our consideration is to buy two water bags with a capacity of 3L.

After all, the water bag is larger, so you can load less water to reduce the load when you don't need too much water consumption, and you can load as much water as possible when you need it. However, when purchasing water bags, we should focus on the use characteristics of water bags, that is, they are mainly used in operation rather than after being stationed. Of course, it is not very realistic to take both into account.

2. Price:

There is no doubt that the higher the cost performance, the better the water bag with the same capacity. But this is not absolute. After all, what outdoor equipment needs most is reliable performance. If it is too cheap or not cheap, but you buy an unreliable equipment, the water bag breaks and seeps in the mountaineering bag, so that the sleeping bag and clothes are blistered. That's a big cup. Therefore, the practicability of design and function is the key. Don't listen to some flashy scientific and technological content and unconfirmed patent performance.

3. Materials used:

At present, most brands of water bags are made of plastic. There are many kinds of plastics, including cold resistant and high temperature resistant. See the following chart for details! Of course, the best material is TPU, which can hold 100 degree boiling water. Of course, it is recommended not to install too high temperature ones to avoid damage to other accessories. After all, not all parts such as suction nozzles and water pipes are made of TPU. The second is eppe / PEVA material. There is no problem with 70 degree water, and they are all resistant to race; EVA material has slightly peculiar smell; PVC material is the weakest, which is not resistant to high temperature, cold and peculiar smell.

Therefore, when choosing water bags, try to choose PEVA / eppe / TPU water bags.

4. Reliability (firmness):

People must step on it and it will not burst. Otherwise, the water bag filled with water may burst suddenly due to the jumping and squeezing of the human body up and down in the bag, as well as the stacking of many bags and heavy objects in the car.

In addition, after collecting water in the camp, the water bags are often left unprotected everywhere. If they are not firmly placed, they can be easily punctured on a sharp stump or stone.

5. Dead weight:

Of course, the lighter the better. This factor can be ignored. After all, the water bag is very light. If it is a handle type water bag, the handle is a little heavy, but it is very light.

6. Convenience: full opening and large opening design

It should be convenient to load water, open and close, lift water, fill water, hang and put around. Therefore, outdoor equipment should be durable and tossing resistant, rather than too delicate and difficult to serve. Full opening water bag, of course, is the trend and the first choice of more and more people. After all, it can meet the requirements mentioned above, durable, convenient and easy to maintain.

Full opening large opening water bag is the first choice of donkey friends and the development trend of water bag in the future. Convenience, easy to use, easy to clean and easy to maintain are the key to the competition of water bags.
