Wavian makes these Water Cans using heavy-duty, BPA-free plastic. These food-grade containers hold over five gallons (22 liters) of water. The opaque resin material prevents the growth of bacteria. UV-stabilization allows for extended outdoor use. A textured, non-slip surface provides increased grip. Wavian Water Cans feature an interchangeable spout and plug, a built-in breather vent, and a bayonet-style closure. Choose your desired color below. Wavian?s custom, easy-pour valve spout allows for no-spill pouring when the can is in the upright position. A space on the inside of the top lid provides storage for the spout. Inserting the plug allows for leak-proof transport. The built-in breather offers a smooth pouring action by eliminating air bubbles. Wavian developed these water cans for use by military organizations around the world. These durable cans are leak-proof. This design makes them the perfect choice for keeping you and your entire crew hydrated! Avoid over-tightening the spout when attaching to the can. We recommend using the Wavian Water Can Opener to prevent damage to the can or spout.
