The local landfill will be thankful when you upgrade from disposable bottles this one holds 14 ounces, and is made of durable Tritan(TM) for long lasting utility. The flip up spout holds up well against chewing and biting. A vent in the leak proof lid ensures continuous liquid flow. The bottle's molded shape is easy for small hands to hold, and the mouth is wide enough to fit ice cubes for cooling down on hot summer days. There's also a built in carrying loop in the lid. It's small enough to fit in lunch bags and most car cup holders, so kids can take their healthy hydration wherever they go. The straw is removable for easy cleaning, and everything can be washed in the top rack of the dishwasher. It's BPA free, but not microwave safe. Recommended for children ages 3+.
