What is BPA?
BPA stands for Bisphenol A which is found in thousands of products. It's the primary chemical used to make polycarbonate plastic. It's found in everything from plastic baby bottles, clear Nalgene water bottles, the liners in many water bottles and canned foods, and is found in more and more products every day. While the FDA allows it to be used and claims there is no danger to humans. But researchers are now finding that exposures below the amounts allowed by the FDA can disrupt the hormone systems of test animals and can affect how their brains function.
Since there is controversy you should avoid exposure to BPA...especially for children. Doesn't it just makes common sense for you to use a Klean Kanteen Stainless Steel Water Bottle (or sippy cup) manufactured by a conscientious company dedicated to making sure you and your family have absolutely no exposure to BPA?
Will using an insulated tote increase the time an insulated mug will keep the contents hot or cold?
The effect is negligible. You might consider a sleeve as a way to hang your insulated mug from something like a stroller.
