Michael B.wrote a review of Backcountry Goat Klean Kanteen - 40 oz on May 1, 2009
I am a hiking guide at the Grand Canyon and put gear through the wringer. Consistently I've been pleased with all my Backcountry.com purchases (which are many), but this time I'm gonna have to be a bit negative. The bottle itself is great, just a problem with the lid. The black top popped of ving the actual "male"aspect of the screw in stopper still in the bottle. It does pop back into place but now that it's happened once it is a reoccuring problem.
