A straw top that grows with your child.

A reusable, medical-grade silicone alternative to plastic sippy lids and single-use straws — gentle on developing teeth and gums, and gentle on the planet, too. Each straw top attaches to regular-mouth mason jars, the Mason Bottle Silicone Baby Bottle, or stainless steel jars, and an X-cut flow valve controls the sip so drinks stay where they belong.

The internal straw is fully removable, so the same top adjusts from early sipping practice to full straw-drinking as your child's skills develop.
