The Klean Kanteen Insulated shares some features with its cousin, the Klean Kanteen Classic. It has a simple and sleek profile, is made of stainless steel, and appears quite durable. Although it proved a better insulator than the other similar bottles in our review, the Hydro Flask Wide-Mouth Insulated, and the Contigo Thermalock Glacier, it also fell (sometimes far) behind its competitors in a number of metrics. This Klean Kanteen is an insulating machine but is not very versatile. See how it stacked up in each metric below.
This contender is a 20-fluid-ounce vacuum insulated bottle. Our tests verified that this bottle is serious when it comes to insulating beverages, both hot and cold. It was also the only stainless steel bottle we reviewed that features a standard stainless steel cap, so you don't have to order an extra cap to avoid plastic altogether. At $30, it's four bucks cheaper than its competition. All these things are great, but this bottle's poor performance in taste and weight, as well as its small volume, held it back from bringing home any trophies.
