Bite-actuated mouthpieces and drink vessels including bite-actuated mouthpieces are disclosed. Bite-actuated mouthpieces comprise a body comprising a dispensing wall, one or more sidewalls extending from the dispensing wall that with the dispensing wall define an internal volume, and an inlet to the internal volume. The self-sealing exit is biased toward a closed configuration and is configured to be selectively reconfigured from the closed configuration to an open configuration responsive to user-applied compressive forces to opposing bite regions. The dispensing wall has a dispensing face opposite the internal volume, and in some examples, the dispensing face is concave.

An apparatus that monitors the consumption of a beverage containing vessel, while the vessel is contained in a pack, bag, or pocket. The method for monitoring includes a sensor that collects data on the beverage withing the vessel, the data may be broadcast to other devices where the data is turned to information and it is displayed. The apparatus may consist of a battery, battery circuit, sensor circuit, temporary storage, sensor, and antenna. Information created may include a warning of when the vessel will be empty relative to the activity of the user.

A hydration reservoir is provided. The hydration reservoir may include at least two panels of resilient material joined together at edges to define a bladder and a bladder volume for storing a liquid. The at least two panels may be deformable as the bladder is emptied of liquid. One of the at least two panels may be molded into a three-dimensional shape.

A backpack and horizontal hydration reservoir combination is provided. The backpack does not extend downward beyond the middle of the back of the wearer, thereby eliminating the need for long shoulder straps and maintaining the weight of the hydration reservoir, housed within the backpack, in a horizontal orientation above the middle of the back.

A personal hydration system includes a curved body that fits over the user's mouth. The curved body includes an integrally molded rearwardly extending tube and a downwardly extending tube that are connected together, forming a passageway. A resilient nipple is optionally mounted to the rearwardly extending tube and is received by the user in the user's mouth. Tubing extends downwardly from the downwardly extending tube and has a free end positioned in a beverage.

A compression garment with an integrated receptacle that provides liquid to a user is disclosed. The compression garment has at least one exterior cavity for receiving a receptacle and at least one tube channel with tube channel openings for receiving the tube from the exterior cavity and to route the tube across the chest of a user and into a webbing loop. An o-ring that locks a breakable foil seal in place is provided when a spout is connected to the neck element and the spout secures the liquid in the reservoir by compressing the o-ring on the foil seal. A grab ridge is then used to release the reservoir from the cavity of the compression garment as desired by the user.

A hydration reservoir is provided. The hydration reservoir may include at least two panels of resilient material joined together at edges to define a bladder and a bladder volume for storing a liquid. The at least two panels may be deformable as the bladder is emptied of liquid. One of the at least two panels may be molded into a three-dimensional shape.

The present invention teaches a system for hydrating a dog during a walk or a jog, including a hand-held rehydrating liquid reservoir, a tube for feeding the rehydrating liquid to a dog collar, and a dog collar that presents the rehydrating liquid in proximity of a dog's mouth. The liquid transport arm may be one quarter or one half elliptical in shape. The liquid transport arm may include mouthpiece which may be a flavored treat, wherein the flavored treat may include holes allowing the rehydrating liquid to pass therethrough for presentment to the dog's mouth.

A bite valve retention system can comprise a base comprising a pivot portion and one or more side portions, wherein the one or more side portions are configured to receive a portion of a strap; and a retention element comprising a first portion and a second portion, wherein the first portion is pivotably coupled to the pivot portion of the base such that the retention element pivots around an axis perpendicular to the pivot portion, and the second portion comprises a first coupling mechanism and extends from the first portion along an outer surface of the base; wherein the first coupling mechanism is configured to allow the retention element to couple and decouple from a second coupling mechanism disposed on an outer surface of a bite valve.

A training device includes a backpack having a first compartment for storage, and a second compartment for hydration, a pair of diagonal braces configured and arranged to accept a number of free weights, a pair of lower support members coupled to ends of the diagonal braces, a spool coupled to each of the lower support members and pivotable and translatable relative thereto, and a resistance band coupled to each spool and terminating in a handle.
