Very large
Awesome bottle, just too large for me. I returned it. It is perfect for people looking for a larger bottle, not one for everyday.

Reliable reservoir
I am impressed with this huge water bottle (40 oz). It provides the extra water needed on those excursions and it fits standard water bottle saddles. I was wary of the stopper but it is leak proof. Love the stainless steel.

Great purchase
I have been using my Klean Kanteen for well over a year and I love it! My water always tastes fresh. The bottle is easy to clean. Unfortunately, it is not dent or chip resistant. I've dropped it numerous times. It definitely looks well used! I did find that I dropped it less when I used the loop cap, instead of the flat cap since I could hook my finger through the loop for a more secure hold.

Best Bottle!
Perfect for backpacking, beach camping, or just everyday use to and from the office. I bought this one to replace my last 40 oz. that I left at school. I really like the top because Klean Kanteen uses a rubber top to sit inside the threaded part which doesn't make a lot of noise when opening or closing the bottle. Great bottle!

Two years and still going
I bought several of these water bottles several years ago when BPA was a hot topic. I pretty much threw out all those Nalgene bottles with BPA and bought these. These Kanteen are so easy to clean. I use the brush to clean the inside of it. The best part is they are stainless steel; so I can rest assure that there is no rust inside the bottles (Yes, I do check them every now and then). I bought one for the office, one for home, and one for my golf bag. I also bought a stainless steel for my hiking trip last year. However, I replaced it with a Nalgene Without BPA this year to save some weight. Overall, you can't go wrong with these bottles. I also bought several others and give them to my close friends and families - as gifts...
