The HydroJug Pro has been redesigned to be both sleeker and stronger than ever. Like the Classic HydroJug, it is designed to help you drink more and stay hydrated! It holds ½ gallon of water, so you won't be wasting your time re-filling your water bottle. The wide-mouth opening makes it easy for you to clean, add supplements, or ice. Our plastic is BPA free and dishwasher safe, so you will always be drinking clean water. With the HydroJug there is nothing between you and crushing a gallon of water per day!
