The material is BPA free so that you will avoid any possible carcinogens. With a reusable bottle, like this one, staying hydrated will no longer be a problem. Our Fluro Sports Bottles will get you moving - especially if there’s a taco at the end! These bottles are super bright, have a fold-down sipper, and a hook so they can hang and they're easy to carry. They also have rubber rings for extra grip when you're all hot and sweaty.
