1. No leakage
Don't miss it. Don't think it's a joke. In fact, the word contains two meanings: firmness on the one hand and safety on the other. The wild environment is bad, and bumps are difficult to avoid. If the kettle is not strong enough, the consequences can be imagined. Similarly, if its opening is not tightly closed, it will not only lose the very valuable drinking water in the wild, but also wet the clothes, instruments and other items. If food, clothing and other important items are killed, it may kill you in some extreme environments
2. Easy to carry
Portability. There are many cases of using water bottles outdoors, sometimes on bicycles and sometimes on rock walls, which puts forward requirements for the portability of water bottles. Some containers made of soft materials, such as water bags and leather kettles, have irreplaceable advantages. Their volume and shape can be changed according to needs, which is undoubtedly the gospel of your overloaded backpack.
3. Designed for special use
Designed for special use, the outdoor environment varies greatly, and there are many kinds of outdoor sports. In some cases, the general function can not meet the needs. When only one hand can be used to drink water, the design of a bottle mouth that can be opened and closed with one hand or with teeth is particularly important. When there are a large number of people and the need for camping and picnic, a collapsible bucket will effectively meet the water needs of the camp. In harsh conditions such as high altitude or polar regions, an insulated kettle that ensures that your water does not freeze will keep you free from worries.
