Contigo Grace is a water bottle made of BPA-free, translucent Tritan copolyester. Thanks to its patented Autoseal technology, the bottle is leak-proof. The Autoseal button is pressed for drinking, and the lid automatically re-seals when released. This allows one-handed use of the ergonomic bottle for on-the-go drinking. Additionally, Contigo Grace is impact resistant and dishwasher safe.
