Outdoor kettle must have function

Water-tight contains two meanings: one is firmness, and the other is safety. The wild environment is harsh, bumps and bumps are hard to avoid. If the kettle is not strong enough, the consequences can be imagined.

Similarly, if its opening is not tightly closed, not only will it lose valuable drinking water in the wild, but it may also wet the clothes, equipment, etc.

Portability, there are many situations in which the kettle is used outdoors, sometimes on a bicycle, sometimes on a rock wall, which puts forward requirements for the portability of the kettle. Some containers made of soft materials, such as water bags and leather kettles, have the advantage of being irreplaceable. Their volume and shape can be changed according to needs.
