With leakproof technology to prevent spills, a protective silicone sleeve to prevent dents + dings, triple-insulation for all-day cold drinks, and a cold-key straw that keeps plastic from sitting in water, the Leap is built to handle everyday adventures. Perfect for school, playdates, and activities on the go, it comes in a variety of fun colors to match your child's unique style. Note: Leap must be in the locked position to prevent spills. There is an instruction manual that comes with it and explains how it works. Recommended for ages 4+.
