360 cups took the world by storm, but they all had one bad feature in common - while they were soft on the inside, they were also rock hard on the outside (the exact place where your baby puts their mouth!).Thats where we come in meet the HYDRATE edge 360, the easiest and first 360 cup with a soft outer lip too! The easy to hold base is topped with a non-spill, 100% super-soft silicone rim. So how is it non-spill we hear you ask? Only the valves that your little ones mouth is touching will open and allow their drink to flow, so you can be sure that the only time your baby is getting liquid out of their cup is when theyre drinking! What's more, we also put hygiene at the top of our list when designing this cup That's why the silicone rim has been made as one, single piece - super easy to remove, clean and reassemble, and doesnt give the nasty germs and bacteria anywhere to hide!
