The 18 oz Classic water bottle is a stainless steel bottle suitable for both kids and adults, designed for quick and convenient hydration. Its single-wall, non-insulated construction makes it lightweight, compact, and easy to take anywhere. Made from certified 90% post-consumer recycled 18/8 stainless steel, it features a durable, chip-resistant Klean Coat finish that supports both people and the planet. The narrow profile of the 18 oz size allows for easier gripping, packing, and carrying. Equipped with a 100% leakproof Flip Seal Sport Cap, the bottle includes an ergonomic spout that opens and closes with a flick of the thumb and can be used with or without the included stainless steel straw for maximum versatility. Ideal for running, biking, hiking, fitness, and an active lifestyle.
