It is a versatile model that combines high performance and usability.
It can be used not only for everyday use, but also in a wide range of applications such as mountain climbing, snowy mountains, and other harsh environments, as well as for outings and as a companion when going to work.
The ultra-light weight of less than 200g is equivalent to that of a smartphone.
The ultra-light weight was achieved by minimizing the thickness of the stainless steel.
The weight of your luggage can be a big stress when you are out and about, but "BONGENBOTTLE" eliminates such worries. You can carry it without worrying about the weight. It is especially useful in severe conditions such as mountain climbing.
Unprecedented heat and cold retention effects
The thinner stainless steel makes the contact area between the inner and outer bottles smaller, reducing heat conduction and greatly improving heat and cold retention. In addition to the improved heat-retaining performance due to the reduced weight, the inner wall of the vacuum section is coppercoated to further enhance the heat-retaining effect. The copper coating prevents heat transfer, which cannot be prevented in a normal vacuum, and blocks heat from escaping to the outside.
Odor and stain resistance
Electropolished to resist odors and stains. The stainless steel surface on the inside of the bottle is uneven at a level that cannot be seen, and dirt tends to accumulate there. The stem is electrolytically polished to a shiny surface, making it resistant to stains and odor transfer after use, allowing for repeated use without worrying about coffee or salty sports drinks, which tend to retain odors.
