保温ウォーターボトル | 二重壁

Took it on a 6-mile hike in July and the water was still ice-cold when I got back to the car—24 hours later, honestly. The double wall really does its job, and I love that there’s no weird metallic taste since there’s no lining inside.

I’m the kind of person who forgets to drink water, but this bottle’s 24-hour cold claim made me test it—ice cubes still clinking after a full day at the office. The steel body has zero weird aftertaste, which is my usual gripe with metal bottles.

Left it in the car overnight in freezing temps and the water was still icy at noon the next day—24 hours cold rating is no joke. The 304 steel feels solid in hand and I love that there's no lining to worry about.
