A bite valve is the part of a hydration system that wears out first, gets chewed by a dog, or goes missing after a wash, and the Comet is the replacement for Hydrapak reservoirs. It self-seals after every sip so the tube does not dribble down your pack strap, a one-hand twist locks it shut for the drive to the trailhead, and the dust cover keeps grit and Gorge dust off the silicone mouthpiece. It is the same valve that ships on Hydrapak's Velocity and Contour reservoirs.
