Heading to the gym? Make sure you are hydrated by drinking from the Tritan-made twist-up tumbler. This 24-oz. tumbler is made of BPA-free Tritan material which is very sturdy, making it shatter and impact resistant. Be sure that you will not spill your drinks with its screw-on spill-resistant top you can drink from by just a twist-up action to release its sipper. The FDA-approved bottle also has a handle which makes it easy to carry. Clean this after every use by hand washing.
