BONGEN BOTTLE “BEIGE”

It is ultra-lightweight, weighing less than 200g, the same as a smartphone.
By minimizing the thickness of the stainless steel, we have achieved an ultra-lightweight design.
The weight of your luggage can be a major source of stress when you're out and about, but the "BONGENBOTTLE" will eliminate that worry. You can carry it without worrying about the weight. It's especially useful in harsh conditions like mountain climbing.

By thinning the stainless steel, the contact area between the inner and outer bottles is smaller, reducing heat conduction and significantly improving the heat retention capacity. In addition to improving heat retention performance through weight reduction, the inner wall of the vacuum part is copper coated to further enhance the heat retention effect. The copper coating prevents heat transfer that cannot be prevented in a normal vacuum state and blocks heat from escaping.

Electrolytic polishing makes the bottle resistant to odors and stains. The stainless steel surface inside the bottle has unevenness that is invisible to the naked eye, making it easy for dirt to accumulate. Therefore, the stem is electrolytically polished to a high shine, making it resistant to stains and reducing the transfer of odors from drinks after use. This means you can reuse the bottle without worrying about lingering odors, such as coffee or salty sports drinks.
