What's the difference between an outdoor kettle and a sports kettle? What are the more famous world brands? Which brand is better?

Outdoor kettle is a kettle carried in outdoor sports. Because it is durable, safe, reliable, convenient and safe, and can have different colors and styles of patterns according to personal preferences, it has become the basic configuration for outdoor enthusiasts. As a tool for carrying water, the kettle is simple in structure and convenient to carry. So it makes no difference. The best is SIGG in Switzerland, followed by Lacan in Spain. The biggest problem of metal sports kettle is that the kettle body is very thin and easy to collapse, and the bottle mouth is too small to be cleaned, so the water capacity cannot be directly seen. NALGENE's space kettle in the United States can avoid all the shortcomings of metal kettles and can hold boiling water. It is the first brand in outdoor plastic kettles.
