The local landfill will be thankful when you upgrade from disposable bottles - this one holds 25 ounces, and is made of durable Tritan(TM) for long-lasting utility. It fits in most car cup holders and has a built-in carrying loop in the lid, so it's easy to take anywhere you go. The bottle has a wide mouth that fits ice cubes for cooling down on hot summer days. With an extremely clear surface that won't craze over time, it's effortless to see the beverage inside. The lid is made of high-impact ABS plastic, with silicone inserts over the spout and vent to make it watertight and leak-proof. The cap flips open easily and locks in place, so it won't swing around while you're drinking. This bottle is entirely BPA free and top rack dishwasher safe. Do not microwave. Recommended for children ages 12 and up.
