It features a unique valve that controls the direction of fluid – liquid flows up into the straw, but does not flow back down. Simply squeeze the bottle until fluid reaches the top of the straw and release. Fluid will stay at the top of the straw, thereby decreasing the effort required to drink. A full straw also reduces the air ingested, and so users experience less coughing and choking while consuming more fluids. Highly recommended for individuals who tend to aspirate or have difficulties generating and maintaining suction (a weak suck).
