Backpacks with cooperatively adjusted hip belt segments and compression strap segments. A backpack includes a pack body, a shoulder strap, and a belt assembly. The pack body includes a back panel and an exterior panel. The belt assembly includes a compression strap segment, a hip belt segment, an adjustment strap, and a releasable fastener. The backpack includes a belt assembly waist loop with a belt assembly waist perimeter. Each adjustment strap is configured to selectively adjust each of the pack volume and the belt assembly waist perimeter. The belt assembly is configured such that, responsive to the user applying a tension force to the adjustment strap, each of a pack volume and the belt assembly waist perimeter decreases by a respective degree that depends upon a ratio of the force required to decrease the pack volume to the force required to decrease the belt assembly waist perimeter.

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.

Some disclosed bladder closures comprise a first rigid member adapted to be secured to a first side of a bladder opening and a second rigid member adapted to be secured to a second side of the bladder opening opposite from the first side. At least one fastener is included for clamping the first and second rigid members together to seal the bladder opening. The fastener is rotatably mounted in the first rigid member and comprises a latch positioned on an outer side of the first rigid member, a shaft that passes through the first rigid member, and at least one tab that engages with a portion of the second rigid member when the latch is rotated. The latch pivots at least partially around the shaft to engage with a projection of the second rigid member that extends through a hole in the first rigid member to lock the fastener in place.

An apparel top for use by a user is worn about a user torso and a user waist. The top includes an outer shell portion having first and second panels, a back panel, shell outside and inside surfaces, and a bottom edge. The apparel top includes a snow gaiter having upper and lower gaiter edges, first and second gaiter ends, and gaiter inner and outer surfaces. The upper gaiter edge is attached to the outer shell portion at the shell inside surface and extends along the first front panel, the back panel and the second front panel. The lower gaiter edge is generally positionable about the user waist relative to the user torso with the lower gaiter edge extending away from the user torso. The top includes a liquid bladder sized and configured to be inflated with a liquid. The liquid bladder is attached to the snow gaiter.

A flexible container device, comprising a container top portion having a top footprint, a container bottom having a bottom footprint, and a flexible reservoir body in between the container top portion and the container bottom. The flexible reservoir body can be formed by a flexible panel folded and attached to itself along one or more body seams extending along a length of the flexible reservoir body. The flexible reservoir body can be collapsible and foldable.

The disclosure relates to a sleeve for use with a canister or other article. The sleeve generally includes a base, a cushioning material coupled to the base, and an outer cover positioned over the base and cushioning material. The outer cover includes at least one accessory portion having at least one strap coupled to a seam of the outer cover and a securement component coupling the at least one strap to the outer cover.

There is provided a sports hydration apparatus comprising: electric componentry housing; an annulus rotatably coupled to the housing, the annulus defining peripheral exterior threading for engaging a threaded opening of a bladder such that the annulus can rotate relative to the housing to screwably engage the threaded opening and wherein the housing and annulus cooperate to seal the threaded opening when the annulus is screwed in; hydration hosing transitioning through the housing in a fluidtight manner, the hosing comprising an interior inlet hose portion which reaches within the bladder for drawing fluid and an exterior outlet hose; a mouthpiece and wherein the outlet hose reaches the mouthpiece; an electric pump coupled to the hydration hosing to pump fluid through the hosing; wherein the housing houses electric componentry comprising: a wireless receiver coupled to the pump and configured for receiving wireless instructions from a dispensing controller device to operate the pump.

A hydration sleeve can include: a band of sleeve material shaped and dimensioned to fit around a user's limb; a bladder pocket connected to the band of sleeve material; and opening extending into the bladder pocket to permit insertion of a hydration bladder into the bladder pocket; and a mouthpiece port extending through the band of sleeve material. Other embodiments and features, including single-use hydration bladders and garments incorporating hydration sleeves are described.

A system for monitoring the volume of fluid in a hydration pack comprises a monitoring unit which is attached to an output of the hydration pack and to a feed tube. The monitoring unit comprises a pressure sensor and a tilt sensor. The pressure sensor obtains a measure of pressure of fluid within the hydration pack that may be used to estimate remaining fluid in the hydration pack. The tilt sensor is able to provide adjustment parameters tor adjusting for changes in pressure due to tilt of the hydration pack. An application on a mobile telephone provides a user with an indication of remaining liquid in the hydration pack. The application provides a visual indication of remaining fluid and may also provide an indication of rate of consumption. The application may also calibrate the system, enabling the system to be fitted to existing hydration pack assemblies.

A wearable fluid reservoir configured to contain liquids includes a swinging suppressing mechanism to inhibit horizontal and vertical swinging of a reservoir main body in relation to a hydration pack in which the reservoir main body is inserted. The pack includes a connecting mechanism that mates with the swinging suppressing mechanism to form a detachable, yet secure fit between the reservoir and the pack. A sipping tube is coupled to the reservoir main body.
