HydroJug Studded Glass Jug. The Glass HydroJug has everything you need to increase your water intake. The ultra-wide mouth opening makes it easy to clean and add ice to your water. The included silicone sleeve slides on and off easily to provide added insulation and protection. You can drink easily one-handed with the fixed oversized handle, and you'll become obsessed with the dual-function spout. Sip without tipping the bottle when the straw is attached or tip the bottle to drink traditionally without the straw. 64 oz capacity. Imported. HydroJug does not recommend using Classic or Pro Sleeves on this product, as they are not compatible and could potentially damage both products. *Open your spout slowly after changing elevation, adding hot liquids, or if your liquid has changed temperature to release pressure within the bottle. *HydroJug does not recommend using this product for hot liquids or other liquids besides water.
