A hydration system is provided. The hydration system includes a container configured to receive and maintain a quantity of liquid, a pump connected to the container, a hose system comprising a plurality of hoses connected to the container and the pump and configured to receive liquid from the container, and an end piece connected to one of the plurality of hoses configured to be used by a user of the hydration system. The pump is configured to circulate liquid through the hose system and container to maintain a relatively similar liquid temperature for all liquid contained in the hose system and container.

A hydration device is provided that includes a sleeve that is worn securely on a limb, such as a forearm, of a user and contains a bladder for holding liquid such as water, sports drinks, etc. The bladder is removable and includes a refill port and a drinking valve. The hydration device can be designed to absorb impacts while being worn, yet is light-weight and flexible enough to conform to the user's body.

A wearable modular carrying system, comprising: a belt; an attachment insert held next to the belt and configured with at least one of a locking post, with a top post prong and a bottom post prong, and a key-hole; and, a modular object configured for reversible attachment to the attachment insert.

Personal hydration systems with cooling and/or warming capability, and the components thereof are disclosed. The personal hydration systems may include a liquid transport system for transporting cooling or heating fluid between a reservoir and a pad, which pad is configured for wearing adjacent to a wearer's body. A pump is provided for pumping the liquid through the system. A drinking tube is connected to the system for removing liquid from the system. Liquid can be removed from the system for drinking by sucking on the end of the drinking tube. A check valve is used to bypass the pump so the user will not have to suck the liquid through the pump. Alternatively, liquid can be removed by spraying the liquid out of the drinking tube using the power of the pump.

Disclosed herein are thermally conductive materials, including, for instance, thermally conductive tubing, thermally conductive devices and/or systems (e.g., apparel, backpacks, and the like), and applications thereof. In at least one embodiment, a thermally conductive material is disclosed that is made from one or more base polymers and one or more additives that increase the thermal conductivity of the thermally conductive material relative to the one or more base polymers. In additional embodiments, a cooling vest and a cooling backpack are disclosed, both of which are wearable by human users to keep their body temperature below a certain value. The vest and/or the backpack may include tubing through which coolant flows. The tubing is placed within the fabric and is arranged so that it contacts the user's skin.

A system for structurally supporting the interior of a fluid reservoir is disclosed. The reservoir can have a reinforcing brace within the reservoir. The brace can be splittable or separable, which can allow the reservoir to be inverted, for example for easier cleaning. The brace can maintain the shape of the reservoir when the reservoir is filled with liquid, preventing the reservoir from forming a cylindrical cross-section. The control of the shape of the reservoir can prevent or minimize distortion of a backpack which is carrying the reservoir.

Provided is activewear with hidden pockets. More particularly, athletic garments such as pants comprising one or more waistband pocket, preferably concealable, are included. In embodiments, athletic garments with an interior concealed pocket in the fold-over portion of a fold down waistband are provided. The waistband pocket enables the wearer to store items such as car keys, hotel room keys and/or smart phones relatively inconspicuously and securely in the waistband of the garment. A purpose of the concealment includes minimizing attention from the items stored within the pocket and allowing the wearer to participate in a variety of athletic sports or events while carrying personal items in a secure manner.

A fluid dispensing bag is provided. The fluid dispensing bag can be worn by a user. The fluid dispensing bag can include one or more storage compartments for storing beverage containers and snacks. A first storage compartment can be accessible from a top end of the fluid dispensing bag and can be separated from a second storage compartment via an insulation panel. The second storage compartment can be accessible via a back panel that contacts a back of the user and can store a fluid reservoir.

A flotation-hydration system to be worn by a user, particularly in a water borne environment, includes a vest assembly dimensioned to at least partially surround the user's upper torso while donned by the user in an operative manner. The vest assembly comprises a plurality of panels securely attached to one another, and a flotation assembly comprising at least one flotation member having a buoyant material of construction disposed in one of the panels of the vest assembly. A hydration support assembly is disposed substantially within the vest assembly and includes a chamber support unit, wherein the chamber support unit is dimensioned and configured to receive a hydration chamber in a supported relation therein. A dispensing tube is routed from the hydration chamber to the front of the vest assembly, for ready access by the user, through a dispensing tube retention channel.

A carrying device for a portable gas exchange device has at least one first holding strap which is designed to be worn around a torso of a patient, thereby allowing the carrying device to be supported on the patient. The carrying device further includes a fastener which is designed to fasten a portable gas exchange device. Also provided is a carrying system which consists of a carrying device and a gas exchange device.
