Klean Kanteen Stainless Steel Water Bottles Reviews

Klean Kanteen (KK) was the first company to introduce a safe alternative to plastic water bottles. Their bottle is made of 304 food grade stainless steel and has an electropolished finish. According to KK, “the electropolish seals the surface and prevents minerals from migrating into the contents.” Klean Kanteen has a safe water bottle that appeals to most everyone.

The company sells the following different sizes: 12oz, 18oz, 27oz and the 40 oz. The slim ergonomic design of the KK water bottle fits nicely in bike water bottle cages and car cup holders. The 12oz, 18oz and 27oz are a little wider than the average plastic water bottle, making it easy to grasp. The 12oz, 18oz and 27oz have a width of 2.75” while the 40oz has a width of 3.5”. The 12oz size is great for kids.

Klean Kanteen stainless steel water bottles offers the option of 6 different tops: the sports cap, the flat cap, the loop cap and the sippy cap, all made of #5 polypropylene plastic and the stainless steel flat cap and the stainless steel loop cap. The sippy cap is designed specifically for infants to make drinking liquids easier. For those that do not want any plastic touching their liquids, I recommend a stainless steel top. If the stainless steel cap is purchased, keep in mind that since the cap is a solid piece, the water bottle can’t be filled all the way to the top as with plastic tops. All KKs have a mouth opening of 1.75” for easy cleaning and inserting of ice cubes. The wider mouth may pose the potential for spilling when drinking, so I recommend a sports cap in order to satisfy a variety of clients. It should be noted, though, that some customers have reported that the sports drinking cap can leak. A very positive feature of Klean Kanteen water bottles is that all of their tops are interchangeable owing to the fact that all of their bottles have the same mouth size.A possible negative for the KK, and actually most stainless steel water bottles, is their lack of insulation. This problem can be solved, though, by purchasing a Built NY insulated tote which comes in a variety of styles and colors. For an additional $2 Klean Kanteen stainless steel water bottles can be purchased in one of the following 6 colors: green moss, orange sunset, ocean blue, black eclipse, pink renewal and tree bark. KK also offers a specially designed bike water bottle cage for the 27oz.
