The triangular shape ensures a secure grip. This lightweight and durable sports water bottle is designed for small hands to hold and control easily. It helps children in kindergarten, school, during sports, and on the go to stay hydrated. The children's water bottle features a silicone sports spout that allows for a smooth drinking flow. The simple push-button opening and flexible carrying handle make it perfect for on-the-go use. Since children can sometimes be a bit rough, the sports water bottle is made from Tritan for exceptional durability. The children's water bottle is leak-proof when closed and spill-proof when open, making it ideal for travel. The buffer at the bottom protects the bottle, even on bumpy rides. The children's water bottle is dishwasher safe (top rack only). With minimal parts, the bottle is more hygienic and easy to clean.
