bobble 34-Oz. Water Bottle: Purify tap water with this water bottle that features a built-in, replaceable filter for clean drinking water on the go. The eco-friendly design is free of BPA, phthalates and PVC, plus a hanger allows easy storage.
The great feature is having the filter inside the bottle... But as most water bottles it only stays cold for a certain period of time... But great for a gym water bottle
