A hydration system for providing fluid to a user. The system includes a bladder configured to hold a fluid, the bladder having a multilayer outer protective skin of a lightweight, durable thermoplastic laminate. A spout is connected to the bladder and in communication with the inside of the bladder and having a relatively large-diameter fill outlet for filling the bladder with fluid. A cap adapted to engage and close the fill port is included. A drinking tube in communication with the inside of the bladder extends from an exit port and includes a distal end upon which a mouthpiece may be mounted. The fill port includes a three-part closure fitting having a sealing base portion, a sealing closure portion, and a sealing cap portion. Each portion includes flanges having mating ridges and troughs to provide a leak proof seal.

1. A hydration system for providing fluid to a user, comprising: a bladder configured to hold a fluid;a multilayer outer protective skin surrounding said bladder, wherein the skin comprises a layer of a chemically resistant composite;a spout connected to the bladder and in communication with the inside of the bladder, comprising a fill port for filling the bladder with fluid; anda tube connected to the bladder and in communication with the inside of the bladder, having a first end connected to an exit port of the bladder and having a second end connected to a fluid delivery fitting,wherein the spout further comprises a multi-part closure fitting that extends at least partially into the bladder and includes an opening through which fluid may enter or exit the bladder, the closure fitting comprising: a base portion, said base portion further comprising a cylindrical neck with an opening therethrough, said cylindrical neck having a first threaded surface on an outer surface of said neck, and a second threaded surface on an inner surface of said neck; and a seal flange attached to one end of the neck, said seal flange extending substantially perpendicular to a longitudinal axis of said neck;a sealing closure portion, said sealing closure portion further comprising a cylindrical body with an opening therethrough, said cylindrical body having a threaded surface on an inner surface of said body, said threaded surface on the inner surface of said body being sized and configured to mate with the threaded surface on the outer surface of said neck; a bottom flange attached to a bottom end of said body, said bottom flange extending substantially perpendicular to a longitudinal axis of said body; and a top flange attached to a top end of said body, said top flange extending substantially perpendicular to a longitudinal axis of said body; anda filler cap adapted to engage and close the fill port, said filler cap further comprising a cylindrical part, said cylindrical part having a threaded surface on an outer surface of said part, said threaded surface on the outer surface of said part being sized and configured to mate with the threaded surface on the inner surface of said neck; and a cap flange attached to a top end of said part, said cap flange extending substantially perpendicular to a longitudinal axis of said part;wherein said seal flange is designed to fit through an opening in the bladder, and wherein said seal flange further comprises one or more indentations to tighten a connection between the base portion and the sealing closure portion. 2. The system of claim 1, wherein the bladder is flexible. 3. The system of claim 1 wherein the bladder comprises an inner layer of thermoplastic polyurethane. 4. The system of claim 1, wherein the tube is connected to the bladder at a different location than the spout. 5. The system of claim 4, wherein the tube is made of flexible plastic. 6. The system of claim 1, wherein the outer protective skin comprises a plurality of durable elastomer layers and at least one fabric reinforcement layer. 7. The system of claim 6, said outer protective skin comprising a fluorinated rubber composite. 8. The system of claim 7, wherein the fluorinated rubber composite comprises a polyamide reinforcing layer and a thermoplastic polymer layer. 9. The system of claim 1 wherein the filler cap is adapted to obstruct the opening through the base portion and the sealing closure portion. 10. The system of claim 1, said seal flange further comprising a plurality of concentric ridges and said bottom flange further comprising a plurality of concentric troughs, wherein said concentric ridges and concentric troughs are sized and configured to engage each other. 11. The system of claim 1, said top flange further comprising a plurality of concentric ridges and said cap flange further comprising a plurality of concentric troughs, wherein said concentric ridges and concentric troughs are sized and configured to engage each other. 12. A closure fitting for use with flexible bladders, comprising: a base portion, comprising: a cylindrical neck with an opening therethrough, having a first threaded surface on an outer surface of said neck, and a second threaded surface on an inner surface of said neck; anda seal flange attached to one end of the neck, said seal flange extending substantially perpendicular to a longitudinal axis of said neck;a sealing closure portion, comprising: a cylindrical body with an opening therethrough, having a threaded surface on an inner surface of said body, said threaded surface on the inner surface of said body being sized and configured to mate with the threaded surface on the outer surface of said neck;a bottom flange attached to a bottom end of said body, said bottom flange extending substantially perpendicular to a longitudinal axis of said body; anda top flange attached to a top end of said body, said top flange extending substantially perpendicular to a longitudinal axis of said body; anda filler cap, comprising: a cylindrical part, having a threaded surface on an outer surface of said part, said threaded surface on the outer surface of said part being sized and configured to mate with the threaded surface on the inner surface of said neck;a cap flange attached to a top end of said part, said cap flange extending substantially perpendicular to a longitudinal axis of said part;wherein said seal flange is designed to fit through an opening in a bladder to which said closure fitting is attached, and wherein said seal flange further comprises one or more indentations to tighten a connection between the base portion and the sealing closure portion. 13. The closure of claim 12 wherein the filler cap is adapted to obstruct the opening through the base portion and the sealing closure portion. 14. The closure of claim 12, said seal flange further comprising a plurality of concentric ridges and said bottom flange further comprising a plurality of concentric troughs, wherein said concentric ridges and concentric troughs are sized and configured to engage each other. 15. The closure of claim 12, said top flange further comprising a plurality of concentric ridges and said cap flange further comprising a plurality of concentric troughs, wherein said concentric ridges and concentric troughs are sized and configured to engage each other.
