Extra-Large Capacity: Our gallon water bottles 256 oz reduce the need for frequent refills, so you can stay hydrated all day—whether you’re training, working outdoors, or on the go. Fill it once and share generously with friends or family
48+ Hours Cold: Coolflask’s GlacioShield technology—triple-layer vacuum insulation—keeps ice for over 2 days, so every sip stays icy and refreshing. Great for beating the summer heat and staying hydrated outdoors, through long workdays, or on the road
Safe & Durable Build: 18/8 (304) food-grade stainless steel ensures safe contact with beverages and a clean taste with no odor. Built to withstand daily bumps and scratches, this metal jug is rust-resistant and made to last—better durability, better value
Leakproof & Wide Mouth: Both the lid and spout are fitted with silicone gaskets to prevent leaks. You can lay it flat in the car without spills. The wide-mouth opening makes it easy to add ice cubes and lets your hand reach inside for thorough cleaning
Easy To Carry: Equipped with a sturdy large handle for grab-and-go convenience, and it also comes with a bonus sleeve that can be worn over the shoulder for easy carrying. The sleeve helps protect the jug from impacts and scratches as well
