ハイブリッドボトル - 再生ステンレス鋼、ホワイト

I’m a commuter so I was skeptical about another leak-proof claim, but this thing survived a tumble in my backpack without a drop. The double wall really does its job—my coffee was still steaming at hour 18, which is ridiculous for how light the bottle feels.

The white finish hides scuffs way better than my old black bottle, and it’s light enough to clip on my bag all day without dragging. I filled it with coffee at 7am and it was still steaming at my evening meeting—that 20-hour warm rating isn’t just marketing fluff.

I’ve been testing the 48-hour cold claim on my commute, and after a full day of ice water it’s still properly chilled at the last sip. The recycled steel body feels solid but not heavy, and the leak-proof lid has survived being tossed sideways in my tote without a drop.
