Adam Johnsonwrote a review of Klean Kanteen 40oz Classic Water Bottle with Loop Cap on July 6, 2013
I have more water bottles than I really need, but I get a lot of use out of them. I generally always have a water bottle at my side. I usually drink out of bottles at home instead of glasses/cups. I really like the 27oz. Klean Kanteen as an all-purpose bottle so I figured I'd try the 40oz. as well. The capacity is nice, and it's the great quality stainless you know and expect from Klean Kanteen. The colors are great - vibrant and shiny. KK uses non-toxic paints, if that matters to you. Overall it's a fantastic product, the only reason I don't use it as much as the 27oz. is that it's just bulkier - doesn't fit in many cup-holders, etc. But what do you expect with 40oz.? I mostly use it as a bedside/around-the-house water bottle.
