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.

The system may be a device that allows for mixture of an additive to a substance in a line of flow. The system may include a hydration pack with a reservoir that may contain a first substance, such as water. The system may include a cartridge with an additive that is mixed to the line of flow through a Venturi which may include a rolling seal that is manipulated with a dial a user manipulates to adjust the amount of additive added to the line of flow. The mixed liquid may then be accessed through a hose from the system to a mouth piece. The system may be modular to allow a user to replace the cartridge by disengaging a first component and a second component of the system through a buckling mechanism and replacing the cartridge within the second component. The cartridges may be reusable, recyclable or disposable.

A moisture removal apparatus configured for partial insertion into a primary opening of a moisture containing container is provided. The moisture removal apparatus includes a first end portion positioned within a moisture containing portion of the moisture containing container. The first end portion has a first material layer configured to absorb moisture from the moisture containing container. The first material layer is further configured to transport the absorbed moisture to a second material layer. A second end portion is spaced apart from the first end portion and extends beyond the moisture containing container. The second end portion is configured to receive absorbed moisture from the second material layer and is further configured for direct air contact for purposes of evaporation of the absorbed moisture.

An outdoor sports backpack includes a backpack body, a liquid storage assembly, a spray pipeline, an atomization module, and a drinking pipeline. The backpack body has a storage cavity, a first pipeline outlet and a second pipeline outlet communicated with the storage cavity. The liquid storage assembly is arranged in the storage cavity and having a liquid outlet. The spray pipeline is communicated with the liquid outlet and configured to pass through the first pipeline outlet to partially extend out of the storage cavity of the backpack body. The atomization module is arranged in the storage cavity and connected in the spray pipeline and configured to atomize the liquid stored in the liquid storage assembly into mist. The drinking pipeline is communicated with the liquid outlet and configured to pass through the second pipeline outlet to partially extend out of the storage cavity of the backpack body.

Multi-functional carrying systems, methods, and devices include a multi-functional carrier bag with a central body from which a first stabilizer strap and a second stabilizer strap extend. The multi-functional carrier bag is usable in first carrying position with the central body positioned at a front of a user (e.g., a front torso or lap). The user can grab the second stabilizer strap and pull the multi-functional carrier bag across their body, rotating it until the central body is in a second carrying position at a rear of the user (e.g., on a back, upper torso). With the multi-functional carrier bag in the second carrying position, the second stabilizer strap extends from a side of the central body to attach to a strap connector disposed on the first stabilizer strap to form a three-point connection (e.g., a T connection) on a chest of the user.
