Insulation for hours. The Stainless Steel HydroJug is the upgrade you need to drink more water. The triple layer insulation will keep your water cold for up to 24 hours. The Jug features a silicone base to keep it where you want it, and never stress about leaks or condensation again! The matte finish is soft to touch and feels great in your hands. The fixed handle makes it so you can still drink one-handed, and you won’t be able to get enough of the dual-function spout. Sip through the attached straw or remove the straw to pour seamlessly. *HydroJug does not recommend using Classic or Pro Sleeves on this product, as they are not compatible and could potentially damage both products.
