How to choose an outdoor vacuum flask in winter?

People nowadays are under pressure, and the fast-paced life makes people feel more pressure.

Many people are looking forward to an outdoor trip. Now that the weather is getting colder, travel friends must need a thermos mug that warms the stomach and heart, so how do we choose an outdoor thermos mug?

First of all, we should look at the safety of the material.

The material of the inner tank is very important for the vacuum flask. We can choose 304 stainless steel and 316 stainless steel, which are safe and environmentally friendly materials. Then you should test the effect of heat preservation. Fill the thermos cup with boiling water and tighten the lid. After 2-3 minutes, touch the outside and bottom of the cup with your hands. If you feel warm, it means that the heat preservation effect is not good.

Finally, check the tightness. We can fill the cup with water, tighten the lid, and put it upside down for a few minutes. If there is no leakage, it proves that the cup is well sealed.
