ขวดน้ำ Rivers จากญี่ปุ่น VACUUM FLASK STEM STD

--------------------------- Rivers Vacuum Flask Stem STD High-spec lightweight stainless steel bottle that makes you want to carry it anywhere from commuting to snowy mountains The "Stem" developed as a successor to the popular stainless steel bottle "Frascar" of Rivers has higher performance. It is a high-spec model that combines usability. The bottle can be used not only for everyday use but also in harsh environments such as snowy mountains. ■ Lightness is justice. The 200g Stem, which is equivalent to a smartphone, has achieved an ultra-light weight of 200g by making the thickness of stainless steel as thin as possible. This is not only for everyday use, but also for activities such as mountain climbing where you want to reduce the weight of your luggage as much as possible. ■ Lighter weight + copper coat for more heat and cold insulation effect By thinning stainless steel, the contact area between the inner and outer bottles is reduced, heat conduction is reduced, and heat and cold insulation is 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. ■ Electrolytic polishing makes it difficult for odors and stains to adhere to the stainless steel surface inside the bottle, which has an invisible level of unevenness that makes it easy for stains to collect. Therefore, by electropolishing the stem and polishing the surface to make it shiny, it is hard to get dirty and the odor transfer of the drink after use can be suppressed, so coffee and salt that tend to retain the odor are included. You can use it repeatedly without worrying about the sports drinks you have.
