Designed with your little one in mind, the Evenflo Feeding TripleFlo Sippy Cup features a 1-piece valve that has an adjustable flow rate. As your child grows, the valve can be easily rotated to a slow, medium or fast flow. The valve can also be rotated to the “closed/off” position, helping to prevent spills when on-the-go or packed away. The lid’s concave design provides extra room for your toddler’s little nose, making it even easier to take a drink. The TripleFlo Sippy Cup is easy to disassemble for quick cleaning and can be placed in the dishwasher (top rack only). Evenflo cups are free of BPA, polycarbonates, PVC and phthalates, and are made of FDA-approved food grade material.
