Klean Kanteen Single Wall Stainless Steel Water Bottle and Bamboo Cap

I admit that this bottle sits on my desk all day, it's not out hiking all the time. I'm sure this is true for most people. After using a wide range of bottles, here is how I settled on the Klean Kanteen:My criteria: I sit at a desk all day and fill this up in the office kitchen. I was only looking for a bottle to drink water out of. I don't like the straw or sippy lids, I just wanted an open mouth design. Also, the ease of cleaning was critical given that I use the bottle everyday and was growing tired of the funk of other bottles. After researching, the Klean Kanteen stood apart:1. Perfect size mouth. Nalgene's are wider, but too wide: if you're not careful, it's easy to spill out the side of your mouth, especially when walking or in a car. Also, the threads on the mouth are uncomfortable. On the other side of the spectrum, I found the mouth of the Sigg bottles to be too small. The size of the mouth matters not only for drinking, but also for cleaning: I felt that I could never get the Sigg clean, whereas this is easy to get inside of with a brush to remove any nastiness that may accumulate.2. Just metal, nothing else: I find that the metal bottles retain less "flavor" than plastic bottles. My Nalgenes and Camelbaks seemed to retain a soapy residue after washing and also the flavor of anything other than water that I placed in the bottle. The Sigg bottles seem like they are just metal, but actually has a plastic coating inside that started to flake away with time. This Klean Kanteen is metal and nothing else, which always tastes clean and is also durable. Although the metal conducts heat more than plastic, this wasn't a concern for me as I don't drink hot liquids out of the this bottle.3. I would, however, get a different cap if you use this in an office or care about noise. Inserting or removing the cap causes a loud metal-on-metal noise that is hard to avoid. Likewise, the loop will hit against the body causing more noise. Although the all-metal construction (other than a small silicone seal) is nice, it's not worth the noise to me. Luckily, the lids are interchangeable. If you don't care about noise, the bamboo lid is quite attractive.My search for the perfect bottle ended when I got the Klean Kanteen. I can't see going back or switching to a different bottle any time soon.

I just received the Reflect in Mirrored Stainless Steel. It is beautiful -- an adjective I never thought I would use to describe a bottle. As my title says, this looks like a bottle Apple would have designed. It is the same shape as the regular 27 oz. Kleen Kanteen bottle, but the polished stainless steel exterior gives it a high-end, simple, and clean look. The cap on the Reflect bottles with their stainless steel shell and bamboo top are different than the caps on the other Kleen Kanteen bottles and, aesthetically, a great match for the Reflect bottles.After an initial washing of the bottle, I filled it up and tested it for leaks. Despite turning the bottle upside down and shaking vigorously no water leaked out, which should be expected. The top screws on and off very easily and quickly -- just one full turn to seal or open the bottle. As it states on Kleen Kanteen's website and with the material that came with the bottle, the bottle itself can be put in the dishwasher. But, the stainless steel cap with the bamboo top should not be cleaned in the dishwasher or submerged in water in order to prevent water from getting inside and creating sanitary issues.I love the fact that the product is almost entirely made of stainless steel, other than the small bamboo round piece on the top of the cap and the one silicon ring around the interior part of the cap to prevent leaking. From an ecological standpoint, it is probably a good thing the product contains no paints, even eco-friendlier ones. I drink a lot of water throughout the day and am using this bottle in place of a glass so I expect the finish to hold up well. If you use this water bottle for more active uses then the polished finish may not be the best choice as I imagine it will show scratches and scuff marks more than the Reflect Brushed finish or the regular Kleen Kanteen stainless steel finish.I was using a Sigg bottle for many years, but recently learned that their bottles -- at least the older ones -- actually contain BPA, which they chose to conceal from their customers. In addition, the coating on the inside of the neck of the bottle was coming off, which made me concerned that I might be ingesting small pieces of the coating material. Given the issues with Sigg, I decided to discontinue using my Sigg bottle and boycott the company's products. The fact that I can put the Kleen Kanteen bottle in the dishwasher is a nice benefit over the Sigg bottles, which need to be cleaned by hand. Another benefit of the Reflect bottle is the one turn on/off of the cap compared to several turns of the Sigg to seal or open the bottle. I think I will be very happy with the Kleen Kanteen Reflect bottle and will probably purchase one of the regular stainless steel bottles for outside use.
