The Klean Kanteen is clean. The way it looks, the way it smells after a few days of use (without wash), and the way the water tastes. Everything about this Kanteen is clean. At a whopping 64oz capacity, this 18/8 stainless steel constructed behemoth will ensure my hydration is maintained. However, in order to carry this big fella along, I had to enlist the help of the Salsa Anything cage( a write up on that will come later, after I figure out how to mount it) which is much more versital than I originally thought. Anyways, once I test this bottle a little more I’m sure I’ll have more to say. Until next time.
