How to choose a good outdoor insulation bottle?

Particular attention should be paid to cold and warm during outdoor exercises in winter. On the way out, it is undoubtedly a wonderful enjoyment to have a sip of warm water at any time, so how to choose a good outdoor thermos?

The material of the plastic parts of the thermos cup is actually very important. It is important to observe and choose food-grade plastics that have a relatively small smell, a bright surface, no burrs and are not suitable for aging. This material is good for both the human body and the heat preservation performance.

The material of the inner tank is also important. Look for 304 stainless steel and 316 stainless steel, which is a sign of safety and environmental protection. When in use, fill the thermos cup with boiling water, tighten the lid, and touch the outside and bottom of the cup with your hands after 2-3 minutes. If there is a warm feeling, it means that this thermos cup is unqualified and the insulation effect is not good.
