I for one have found lately that I am using an inordinate amount of plastic bottles lately as I have made an extreme effort to keep hydrated this summer. Between the Gatorade and Dasani bottles, it's a bit much to say the least...
So we partnered with Nalgene to start using their BPA free 32 oz Nalgene Bottles, and well not only is the hydration issue taken care of, but I'm not recycling a whole case of plastic stuff a month!
We've done these for the Appalachia Service Project and they have used it for a fundraising gift with great success.
Look to using these for any sports-related promotion or fitness program!
