Smarter (and tougher) than the average sippy cup, the OXO Tot Transitions Soft Spout Sippy Cup has a patented, almond-shaped straw that opens with just a light suction and stays closed the rest of the time. That means it won’t leak when dropped or thrown. Use it with or without the removable handles or with any of the other interchangeable lids from our Tot Transitions line. Designed to be extra comfy in little hands, this Cup encourages tots to help themselves. Measurement markings along the side help parents track progress, while the hinged cap protects the spout and prevents spills on the go. Cap and spout come apart for thorough cleaning. Dishwasher safe.
