Klean KanteenWide Mouth Double Wall Insulated Water Bottle with Loop Cap

This water bottle is easy to clean, doesn't scratch easily and is so stylish and pretentious that one might actually feel compelled to carry it around with them on a daily basis - or to use it to carry water while riding a unicorn long distances.My first Klean Kanteen water bottle was one of my favorites - durable, but collected scratches and small dents at every minor mishap. This water bottle was not insulated and had a narrow mouth - which made it was somewhat difficult to clean. After I lost this water bottle, I thought I'd take the opportunity to upgrade to something sleek, stylish, and sexy.In the sea of gleaming stainless steel 20oz water bottles, this one stood out from the waves. It's slim shape and modern color options were what first drew me to this Klean Kanteen. Was this love at first sight? Perhaps.I anxiously awaited the delivery of my new water bottle. Like a small child at christmas, dressed in my pajamas, I stealthily hid behind the door, hoping the UPS delivery person wouldn't see me. Not even my sheer excitement for receiving THIS water bottle could overcome my crippling social anxiety. Once the delivery person had vanished, I seized the small brown package and, with the brute strength of a mountain troll, gently removed the packaging tape from around the opening of the box.I believe angels were singing as I pulled from the plastic packaging what was to become the best water bottle I have ever owned. The cap twists on and off with ease, yet I never have to worry about the top coming off because the sturdy construction of the metal lip of the bottle and the cap fit together like Lego pieces - perfectly.The plastic coating is strong, and does not scratch easily. On one dangerous run in with a door frame while this water bottle was dwelling in my back pack's water bottle holder, it did obtain a scratch - but it is hardly noticeable since the finish on the plastic is not obnoxiously shiny.The stainless steel at the top and bottom of the bottle have not dented in any way - even though I have accidentally dropped this water bottle while saving princesses from dragons, or being a ninja with mad skills, and so forth. The silver at the bottom does reveal scratches more obviously than the plastic colored part of the bottle However, I also tend to abuse my water bottles - so that is to be expected.This water bottle keeps my coffee hot for longer than many of my travel coffee thermoses do! On the flip side, it also keeps my water ice cold for almost the entire day - even when the temperature outside is extremely hot. When dispensing liquid into this water bottle for later consumption, anticipate that the temperature will not change drastically in a short amount of time.The larger mouth of this bottle also makes it very easy to clean in comparison to my old water bottle.My only real complaint is that the temperature of the beverage does not ever seem to return to room temperature. This is by far my favorite water bottle for daily use - I can fill it up in the morning and it stays cool all day. However, when I'm working out at the gym, I like drinking room temperature water rather than ice water. Since this water bottle holds the initial temperature of the water so well, I can't just wait a few minutes for the water to become less cold [like I could with my non-insulated Klean Kanteen]. I guess that you could say this water bottle works TOO well.In summary: Best water bottle I've ever purchased! Works so well that it actually causes problems. I would recommend this water bottle to everyone I know, and plan to buy several more!

I have the brushed stainless 12oz./355ml. insulated bottle.I am not a "save the planet" sort of guy . . . so the hype about REDUCE, REUSE, RECYCLE was not the reason I looked at the Klean Kanteen. I do believe this company DOES care about that stuff and I respect them (and you if you are so inclined) for it. I was drawn by the design of the bottle itself, the stainless steel on the bottom of the Loop Cap, and the overall quality of the bottle. The company also seemed very honest in their product descriptions (temperature retention, etc.) and literature. I do not mind paying a little more for a quality product.The Loop Cap is sturdy and easy to carry. No sharp edges on the cap or bottle. As a matter of fact, I was a bit worried that the bottle might slip/bounce out of my backpack as I ride my bike to work. Happily, the 12 oz bottle is short enough that it rides pretty deep in the side pocket that seems designed for such things. NOTE: the insulated bottles are a bit too narrow to safety ride in a typical water bottle wire holder on a bicycle.The wide mouth of the bottle really helps with cleaning the inside. It also makes it possible to use large ice cubes in the bottle. The rim is narrow, but not sharp and is comfortable when drinking or eating right from the bottle. I have not had any leaks or difficulty getting the cap on or off. No issues with flavor transfer; garlic-laden soup one day, Gatorade the next.The container performs at least as well as advertised whether using hot or cold contents. After an hour long commute in the morning, the oat groats or wheat berries I prepared the night before are still quite warm and ready to eat. I even put a whole raw egg, the shell, in with my groats one evening and enjoyed a perfectly hard boiled egg and warm groats the next morning!I would recommend this to a friend. As a matter of fact, I ordered a 20oz size as well. What the heck, I guess I also enjoy helping to save the planet!

I specifically purchased from this company because of the reputation and having another canteen. The black looks sharp and I use it primarily indoors at the gym and mix my protein based shakes. I highly suggest getting a bottle washer to clean it out, which I do shortly after use. The top screws on and off easily, securely, and I love the wide mouth. This is not a sippy canteen and is much more sanitary, capable of not leaving residue in small crevices to generate mold.It will scratch but it is otherwise resistant with some type of coating on the outside. It will dent when dropped, but I'd have to say that this would likely be true with almost any aluminum bottle. Just don't drop it! Overall I think the design is well made and the top area makes it easy to carry with fingers, thanks to good thought behind the manufacture.OK - does it keep drinks cold/warm? Yes it does. I've had it keep for several hours. People have ridiculous expectations and if you're looking for 4-8 hours, I've found that ice will mostly melt but the liquid is still very cool or possibly cold. I use a different color on my bike because black soaks up the sunlight, but surprisingly the liquid still stays mostly cool.I haven't had a sweating problem with the bottle either although I think the cap might sweat just a little. I'm very impressed by the bottle and, if you get it at any slightly discounted price, I think it will be a far better investment than going no-name and going cheaper.
