It is a versatile model that combines high performance and usability.
It can be widely used not only for everyday use, but also for going out from harsh environments such as mountain climbing and snowy mountains, and as a companion when commuting.
It is super lightweight, weighing less than 200g, which is equivalent to a smartphone.
By reducing the thickness of stainless steel to the utmost limit, we have achieved ultra-lightweight.
The weight of your luggage can be a big stress when you go out, but "BONGENBOTTLE" solves that problem. You can bring it without worrying about the weight. It is especially useful in harsh conditions such as mountain climbing.
Unprecedented heat and cold insulation effect
By making the stainless steel thinner, the contact area between the inner and outer bottles has become smaller, heat conduction has decreased, and heat retention and cold retention have been greatly improved. In addition to improving the heat retention performance by reducing the weight, a copper coat is applied to the inner wall of the vacuum part to further enhance the heat retention effect. By coating with copper, it prevents heat transfer that cannot be prevented under normal vacuum conditions, and blocks heat from escaping to the outside.
Difficult to smell and stain
Electrolytic polishing makes it difficult to get odors and stainsThe stainless steel surface inside the bottle has an invisible level of unevenness, which makes it easy for dirt to collect.Therefore, by electropolishing the stem and polishing the surface to a shiny finish, it is difficult for stains to adhere and the odor transfer of drinks after use can be suppressed, so coffee and salt that tend to retain odors are included. You can use it repeatedly without worrying about the sports drinks you have.
