The CamelBak Eddy + has a bite valve that is opened by gently biting on it. This silicone bite valve is connected to a straw that makes the liquid rise when you suck. So you don't have to tilt the bottle while you drink. The spout closes completely when you stop biting it. If the bottle falls out, it's not a problem, the liquid is well stopped by the occlusion valve.
