Pressurized hydration system

A hydration system, comprising:

• a pack wearable by a user;
• a bladder having a sealable compartment for holding a liquid, the compartment being formed by opposing flexible walls,
• a drinking tube having a first end with a valve and a second end;
• a first port configured to receive pressurizing gasses into the compartment;
• a baffle connecting the opposing walls within the compartment, the baffle configured to oppose expansion of the bladder as the pressurizing gasses are introduced into the compartment;
• a second port formed in one of the opposing walls configured to couple to the second end of the drinking tube to provide fluid communication between the compartment and the drinking tube;
• a third port formed in one of the opposing walls through which the liquid can be supplied into the compartment;
• a pressurizer configured to detachably couple to the first port, the pressurizer operable to supply the pressurizing gasses for pressurizing the compartment when coupled to the first port, the pressurizer being integrated into the pack;
• a transfer coil having a first end coupled to the first port and a second end coupled to a fourth port, the fourth port defining an entry from the transfer coil into the compartment, the transfer coil having a surface positioned to be in at least indirect contact the liquid in the compartment;
• and
• a cartridge holder configured to detachably couple to the first port, the cartridge holder configured to hold and to cause a cartridge to mate with the first port allowing pressurizing gasses to expel from the cartridge into the compartment via the transfer tube;
• wherein, when sealed and pressurized, activation of the valve unseals the compartment and allows the liquid to be expelled from the compartment via the second port and the drinking tube as a result of a pressurization of the compartment by the pressurizing gasses;
• and
• wherein pressurizing gasses when expelled from the cartridge have a cooling effect transferred to the liquid via the surface while pressurizing the compartment.
