mountain mommy wrote a review of Nalgene Tritan Grip-N-Gulp BPA-Free Bottle on June 4, 2009
Normally we use the camelbak bottles in our house, but my six year old is a chewer and the bite valves on them do not last with her. I have used the regular nalgene bottles, but being six she does not always pay attention and often will wear a bit of the water from those if she is not careful. This one she can walk and drink her water at the same time, can't really do much damage to it (though, when I washed it I noticed a few teeth marks around the valve, but nothing that hinders its performance). She doesn't really have it laying down or just tossed in her backpack much so we haven't really had the chance to test out some of the leak issues others have had. So far, it works great for her!
