Mizu S4 Insulated Water Bottle

                                 “There are great companies who genuinely care about the environment and are dedicated to creating earth-friendly, reusable products. Mizu safely falls into this preservation category, and then takes their stewardship one step further.”

The Tech Stuff

We tested the 13.5oz./400ml., narrow mouth Mizu S4 Insulated Bottle, retail $28.95 USD. Part of a slender new design series, this insulated bottle is made with double-walled steel and copper, and water stays cold for 24 hours. The S4 is made with 18/8 food grade stainless steel, and is corrosion resistant. It comes in six colors, is accessory compatible and, as with all Mizu products, has a lifetime guarantee.

Why test Mizu bottles?

It’s simple really—they were nice enough to send us one. Why tell you about it? Thankfully, that has a simple answer as well. There are great companies who genuinely care about the environment and are dedicated to creating earth-friendly, reusable products. Mizu safely falls into this preservation category, and then takes their stewardship one step further. The brand is helping to reduce the need for plastic water bottles through their non-profit foundation—www.protectingwhereweplay.org –by proactively placing free-to-use water stations in skate parks, mountain resorts, beaches and other recreation areas. All of these well-placed intentions wouldn’t mean a whole lot though, if they didn’t have a solid product as well. Thankfully, we really like their bottles…in fact, we kind of love them.

 

The Experience

Right out of the box I loved S4‘s sleek look, and glossy desert design. After perusing the website a few times, it was easy to spot another product or two—or five—I’d like to have around. In addition to the styling, where Mizu really shines is in the well thought-out construction, made with high-quality materials. Water tastes fresh, without any metallic flavor, and there’s no worry of toxic chemicals leeching into your drink. I cringed when I tossed the bottle about in a pile of boulders, in an attempt to speed the wear-and-tear process, but the S4 survived with only a few minor dings to the glossy coating. For a healthy water drinker, the 13.5oz. will be a bit small, so either plan on trips to refill, or be ready to spring for the bigger version. One advantage of the smaller bottle was the packability. Thanks to the incredible insulation, I filled the S4 with water and ice and slipped it into my running vest, before heading to the mountains for a long trail run. Four hours later, after being exposed to mid-day full sun, my back-up water was deliciously cold, and still had ice. Bliss.
