In general, when you are hiking, even if there is no water supply in the middle, the water bag is full of 2-3L of water, which is enough for a day's walk.
However, in the extreme case of sultry heat, it may not be enough to drink 6L of water. In addition, it needs to be used for watering, cooking, and brewing tea after camping. When the camp is some distance from the water source, in order to avoid round-trip Water consumption consumes energy, wastes time, etc., you can consider buying a 6L water bag.
After all, the water bag is bigger, you can put less water to reduce the burden when you don't need too much water consumption, and you can install as much as you can when you need it.
water. The 2-3L water bag obviously cannot meet the needs of various complex environments, or it needs to increase the number of water strokes and consume more physical energy.
2, the price

If it is too cheap or not cheap, but bought an unreliable equipment, the water bag ruptures in the mountaineering bag, so that the sleeping bag and clothes are
Blisters, that is very troublesome.
3. Reliability (firmness):
It must be stepped on without bursting, otherwise the water bag filled with water will be squeezed in the bag with the front and back of the human body, and the weight of many bags in the car may cause the water bag to burst suddenly. . In addition, after the water is raised in the camp, the water bag is often unprotected and placed everywhere. If it is not strong, it can be placed on a pointed tree column and a pointed stone.
Easy to be punctured. Therefore, water bottle brands that are easy to pick up, leak, water, and bad reputation should not be bought.
Of course, the lighter the better. But it is still necessary to consider the trade-off between weight and firmness. If it is heavy and reliable and light and easy to break, then it is better to choose heavy and reliable.
It is convenient to install water, convenient to open and close, convenient to lift water, convenient to pour water, convenient to hang, and convenient to lay around (ie not easy to damage).
