Love it!

  • Familiarity: I've put it through the wringer

I use this bottle for everything. I bring it to the gym and to work. The size works great for almost anything. Not too big or too small. The cap shuts tight so there is not any leakage when set on its side. The top is wide enough to fit standard size ice cubes too.

If you're looking for a basic do it all metal bottle look no further!

Keen on the Klean

    Nice cap and solid construction. This will last for ever.

    Great for the office

      This is my work water bottle. I only drink water out of it so I rinse it out instead of washing it. It's very lightweight, I just wish the lid was somehow attached so it would never get lost.

      All bottles should have a rounded lip

        If it got lost I'd get the exact same one.

        goes everywhere with me

        I love this one and have owned many others. It fits perfectly in my timbuk2 laptop work bag. It can sweat a bit but the ones that don't are real heavy. This one is supper light. I like the one with the loop in the lid better so i can put a carabiner on it and hook it on my pack when i hike. - just incase it slips out of the pouch on the backpack.

        I use it everyday

        • Familiarity: I've used it several times

        This water bottle fits in my car cup holders, backpack. Water just seems to taste better coming out of a metal container and I'm able to put ice in this size. I really only worry about dropping this bottle and denting it. It will also fit in vinyl covered bike holders, if you are thinking of using it for cycling.

        save countless plastic bottles

        I work in agriculture, which means long hours in the summer sun, hydration is the difference between a productive shift and a debilitating headache. This is a convenient bottle size, and the tapered neck makes it easy to drink on the move. I used to keep my recyclable bottles in a bag on the passenger side floor board, and in just a weeks time I'd fill a hefty bag. Now I simply refill my bottle as often as needs be. The 27 oz classic bottle fits nicely in any vehicle cup holder. I've also taken these on the trail but if you're concerned about cutting ounces there are lighter options. The brushed stainless bottles are also great in the event you should need to bring water to a boil. Also check out Klean Kanteen's wide mouth bottles!

        Love them

        • Familiarity: I've put it through the wringer

        No plastic taste and a much better neck design than the Sigg bottles (easier to clean both inside the bottle and the thread).

        Awesome water bottle.

        • Familiarity: I've put it through the wringer

        I have been looking for a water bottle since my Nalgene bit the dust a while back and my Klean Kanteen has been SO great. I use it everyday and am impressed by how cold it keeps my water. It had a bit of a funky odor inside the bottle itself initially when I first received it, but after washing it with soap and water my water has tasted crisp and refreshing. I decided to buy my kanteen in the color "Violet Storm" and I absolutely love it. Super cute and I get compliments on it all the time! Definitely recommend this product to anyone looking to move away from plastic products.

        great bottle!!

        • Familiarity: I've used it several times

        I've had this for a few months and it just lives in my car, great for communiting, not heavy and it doesn't make the water taste yucky.

        definitely a favorite!

        Great for seasonal use

        • Familiarity: I've put it through the wringer

        I have two of these in the stainless finish and they perform as expected. The pros: no metallic taste, fit well in my pack side mesh pockets, seal well, and easy to clean. They’re the best metal bottle I’ve tried. Just be aware they’re metal, a great heat conductor. I don’t use them in winter, and they warm up a bit when exposed to the sun on a hot summer day. In winter I stick with a Nalgene or go to metal insulated bottle if I want something hot.

        I've had this water bottle for over 7 years! And it's still going strong! What a great investment. I have the black 27 oz. It's a little banged up and scratched on the bottom, but this has not compromised the effectiveness of the bottle. My biggest praises-- water tastes good (doesn't taste like plastic); it does not smell bad like some water bottles do after not washing them for a while; the cap screws on well, making it leakproof; the cap makes it easy to tie/clip to backpack. The 27 oz is suitable for me because it's slim. It's fits in most cup holders, backpack pockets or even a big purse.

        The last convenient feature--flip the cap over, and you can use it as a shot glass! ;)

        Very convenient

        • Familiarity: I've put it through the wringer

        Awesome to keep in your pack or carry along with you anywhere.

        I own the 27oz and 40 oz stainless.

        Great for backpacking or camping.

        Being a single wall in stainless, in a pinch, you can throw this over an open flame.... just remember not to do it with the insulated double walled ones.

        The rolled lip on the top is great. Does not pinch or catch any skin of the lip. It will sweat (to be expected) if you have ice water on a hot day for example. If you add hot items, take the lid off, you will build pressure and damage the bottle. Remember not to leave liquids in it and have it freeze over on you. You'll deform the bottle.

        The paint seems durable enough for everyday use, I figured over some time and abuse it'll start to peal off (happened to my buddy's) that's to be expected. If you're concerned about that, go stainless. I like the attitude.

        Ah, most important.. you don't get that metal taste in your mouth since it's 18/8 food grade stainless steel.

        How about some weight measurements.

        Cap = 28.6 Grams

        Bottle (empty) = 181.6 Grams

        Great bottle, lots of dents

        • Familiarity: I've put it through the wringer

        I really like this bottle - the profile is great, it fits well in backpacks, it's easy to drink from. Stainless steel is the best as far as water bottles! Unfortunately the bottom edges don't put up with the beating I dole out, but I guess that just adds character.

        Pretty good stainless bottle

        • Familiarity: I've put it through the wringer

        I really love drinking from stainless vessels, and found this one to be really pleasant to drink from, like the profile of the bottle as well, also very easy to clean odors out of compared to plastic alternatives

        Be wary of dropping it though, as the edges on the bottom appear to dent easily, which then causes the bottle to not sit on a surface properly; very doubtful this would completely break, however
