  • Familiarity: I've put it through the wringer

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

Favorite bottle!

  • Familiarity: I've used it several times

The 27 oz size is great. I have many nalgenes, but I like the slim size of this bottle both for backpacking AND every day use. It fits in the cup holder in the car and I can even slip it in a large purse. Probably my favorite feature is that it does not take on the smell of things you put in there.

happy bright colors and durable

  • Familiarity: I've used it several times

took a few washings to get the weird smell out....but i love the happy bright YELLOW and durability of this water bottle!

Great companion

Whether I'm at home, at work, on the trail, or driving, I generally always have a water bottle at my side. I've used a lot of different brands - I like Nalgenes in the backcountry, I dig HydroFlask for thermos-purposes, but when I want a general all-purpose water bottle to carry around, I recommend Klean Kanteen. The lightweight 27oz. is just perfect - it fits in pretty much any cup-holder, it can clip to anything without weighing much, it can fit in pockets, and it's made from superior quality stainless steel. The colored finish is always vibrant, shiny and attractive. And it's a great company to support. Don't hesitate to pick one up.

Dents Quite Easily

  • Familiarity: I've used it several times

I like my bottle, easy to maintain (just throw it in the dishwasher), but I already dented it sadly. It was full of water and dropped onto hardwood floors from about 5 feet. I was hoping it wouldn't dent that easily. Interestingly, Nalgene bottles are stronger, but you couldn't boil water in it in an emergency! So this steel bottle is better for that. :)

Everyday, all purpose bottle

  • Familiarity: I gave it as a gift

Gave this to a friend. She loves the fun color and durable finish.

One caution: the cap can leak if not tightly secured. She gets around this by clipping a carabiner to the clip for extra leverage to aid in tightening.

BPA Free

I really like these bottles for the gym or office. They are more environmentally friendly and in a surival situation you could boil water if you didn't have a pot. I stumbled on this guy's site that solely reviews water filters/bottles and he did a great review. Scary fact that Aluminum bottles leeched BPA into water. For backpacking I still use nalgenes, mostly because the one I have can't fit my steripen.

A handy addition to the arsenal.

My love for my Klean Kanteen bottle stems from a single experience wherein I left a tea bag and some water in the bottle for a month. Basically something grew in it, and I washed it thoroughly (soap, some scrubbing).. lo and behold, no residual smell or taste.

That aside, I use my bottle mainly for hiking trips when my pack is so full it makes it hard to fit a Nalgene in the water bottle pockets. I like the ease it adds in pulling the bottle in and out. I have a lovely green bottle, but do be warned that the color does chip eventually if you have anything but the brushed metal finish.

Great bottle
I also love my bottle, size is great. I tried freezing some water in the bottle about 1/2 full, it works well, but the bottom of the bottle bowed out and now it will not sit up. I don't care, cause it use it anyway and the ice stay solid about 6 hours, I just keep adding water to the bottle to keep me some ice water all day while I work. The paint is coming off around the bottom where it is bow, but it's a working bottle. I freeze it each night. No leaks, or spills. Note - I do not freeze the lid on the bottle - make sure you take it off.

Michael - Have you tried taking a hammer and gently tapping the bottom to fix the bowing? I've done it before on a steel bottle like this and it worked like a charm.

Responded on

Michael next time try freezing 1/2 filled water bottle on it's side and you won't have that problem.
