- Recessed threads on the lid and bottle result in dribble-free drinking and a no-drop seal
- Keeps cold drinks cold for 40 hours, and hot stuff hot for 12
Price: $30 (18 oz)
Weight: 343.6g (about ¾ pound)
If, like me, you have piles of water bottles you don’t use, it might be time to narrow down your collection to include only the ones you absolutely love. I love the Zoku stainless-steel bottle. It’s pretty—the Paradise pattern has garnered many compliments and makes me happy just looking at it. It’s durable—my bottle has done its fair share of rolling around in a beach bag and under the passenger seat of my car without suffering dents or scratches to the floral surface. And it keeps the cold stuff cold and the hot stuff hot. And because this stainless-steel option is heavier (about ¾ of a pound), and therefore more stable, than a typical plastic water bottle, it’s less likely to topple out of your kitchen cabinet and ricochet off your head.
Dribble-Free Opening
Recessed threads on both the lid and the bottle result in a smooth, dribble-free mouthpiece and no-drip seal when the lid is secured, and a removable paracord lanyard gives you carrying options. At its narrowest point, the bottle’s opening is 1¼ inches in diameter, meaning if you still use good ol’ fashioned, standard plastic ice trays like I do, the cubes won’t fit without first smashing them to smithereens. Those skinnier, half-moon cubes that most refrigerators automatically spit out slip through the bottle’s opening, no problem. If you like a mouthpiece that you can pull open with your teeth and slam shut with your palm, this is not that.
Water—and, Ahem, Whiskey—Stays Cold
I came across this bottle during my quest for accessories for another Zoku product, the Single Quick Pop Maker. I wanted extra sticks so I could make and store frozen whiskey sour pops—because, admit it, how tasty would that be after a hot summer run? It didn’t work; the whiskey didn’t freeze. But the stainless steel bottle did an amazing job keeping that same cocktail chilled during a steamy day at the beach. Yes, I used it for water, too. In fact, I filled it in the morning and let it sit in my hot car until I finished a lunch run at our local rail trail. The water was still cold. Zoku claims it keeps things chilled for up to 40 hours, hot for 12. I filled mine with coffee at 3 a.m. ahead of a 7-hour road trip and had the pleasure of sipping—without dripping—a hot beverage the whole way.
