With a dual-function lid, they can sip through the No-Perse soft straw or switch to the chug spout when they're extra thirsty. The leakproof design, lid lock mechanism, and venting technology mean no unexpected spills in backpacks or lunchboxes, even with temperature or altitude changes. Plus, the water-level window makes it easy for both you and your child to see when it's time to refill. | Hydrojug 14oz Ease2o Straw Water Bottle | Size 14 oz
