Jacob ★★★★★ Oct 21, 2026

The double-wall insulation really works—my coffee stayed warm for hours without the glass getting hot to the touch. It’s also nice to finally have a water bottle that doesn’t leave a plastic taste in my mouth.

Kevin W. ★★★★★ Oct 19, 2026

The leak-proof lid is a lifesaver—tossed it in my gym bag upside down and not a single drop escaped. The grey glass feels cool and substantial in hand, and water tastes completely clean, no weird plastic aftertaste.

The glass core really does keep my water tasting pure, no weird plastic or metal aftertaste at all. It’s been a week and the double-wall still keeps things cold for hours, and the leak-proof cap is perfect for tossing in my bag.
