A container having enhanced wall integrity with a rotational element and a stacking feature is provided. The container includes a sidewall having an alignment structure formed along a height of the sidewall and an upper stacking shoulder formed above the alignment structure. The alignment structure is adapted for orienting the container with respect to a second container so that the alignment structures of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The upper stacking feature is formed into the sidewall of the container and includes a radially extending wall portion and an upwardly extending wall portion that together form a stacking corner. The stacking shoulder is provided above the alignment structure facilitates nesting of two containers when stacked together.

Provided is a storage device including a storage body for holding a liquid, a gas or an item, which has a first wall, a second wall, and a magnetic closure device for closing the storage body, which has a first closure part and a second closure part. The first closure part has a first strip body elongate along a transverse direction and is arranged on a first closing portion of the first wall. The second closure part has a second strip body elongate along a transverse direction and is arranged on a second closing portion of the second wall. The first closure part and the second closure part cooperate in a magnetically attracting manner. At least one of the first wall, the second wall, the first strip body and the second strip body are wholly or partly fabricated from a composition containing an antimicrobially active additive.

In embodiments, the invention is a novel hydration pack refill system that comprises a fluid bladder, a bag for carrying the fluid bladder, a bladder nozzle for refilling the fluid bladder, a clip for sealing the end of the bladder nozzle, and a refill port for accessing the bladder nozzle through the bag and methods for its use. The invention may further comprise a water tube and a mouthpiece to allow a user to drink from the fluid bladder while wearing the bag. In preferred embodiments, the bag may be worn on a user's back, held in place by a pair of shoulder straps, and may be rapidly refilled by reorienting the bag from a vertical orientation to a horizontal orientation, opening the refill port, extending the bladder nozzle, removing the clip to unseal the bladder nozzle, and refilling the fluid bladder via the bladder nozzle.

A smart hydration reservoir includes a flexible sensor which can be attached to the outer surface of any kind of the hydration reservoir and monitor changes of capacitive data of the hydration reservoir while user drinks the liquid which makes changes of the liquid level. The capacitive data is inputted into the controller; the controller will calculate the liquid level and then send out the information of the liquid level to the hand held device, such as specified display or mobile phone. Thus, the user can easily notice the liquid level of the hydration reservoir. The whole hydration detecting assembly can be easily installed to any hydration reservoir bought from the market.

A suit for water-based sports, comprises: a closable compartment within the suit, the closable compartment positioned to be located on the back of a wearer when worn; and

an opening for a drinking pipe, the opening positioned to allow the pipe to lead from the compartment to a face of the wearer.

A wearable hydration system, bladder ensemble and hydration kit enabling hands-free user hydration. The wearable hydration system, ensemble and kit include a liquid-impermeable bladder, a conduit element, and a wearable mechanism. The bladder includes front and back bladder walls and at least one, but preferably a series of particularly configured seals that seal the front and back bladder walls or sides. The conduit element is inserted into the liquid-impermeable bladder in lateral adjacency to the seals for conducting liquid from the liquid-impermeable bladder to a user's mouth. The wearable mechanism may be exemplified by a pouch formation. The pouch formation received, holds, and positions the liquid-impermeable bladder relative to the user's body when donned by the user. A series of matable fasteners may fasten the bladder to the pouch formation via a series of fastener-receiving apertures particularly formed in the bladder and pouch formation.
