A personal hydration system with an improved mouthpiece for use in providing fluid for delivery to a user. The mouthpiece includes a neck (28) that is adapted to be mounted on a supply tube (22) to a hydration system and which is joined to a resilient head (30). The head (30) includes a dispensing face (32) with a pair of lips that define a normally closed slit (38), through which fluid is dispensed through the mouthpiece, a perimeter (34) and a minimum dimension (36) between opposed points on the perimeter (34). The bite region (44) extends from the perimeter (34) to a lip-receiving shoulder (46), which extends from the bite region (44) to the neck (28) and the bite region (44) has a length measured from the perimeter to the lip-receiving shoulder (46) which is less than the minimum dimension (36). From a closed position, in which the lips extend against each other to close the slit (38) and prevent fluid from being dispensed through the slit (38), the mouth piece is deformable to a dispensing position in which the lips are spread at least partially away from each other to allow fluid to be dispensed through the lips.
