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; an 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 wetsuit is provided which comprises (a) a first central region comprising a first material and having a first thickness; and (b) a second lateral region comprising a second material and having a second thickness. The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

A wearable weapon restraint system is provided. The system includes a cable having a proximal end and a distal end, a retractable cable reel configured to contain the cable and allow the cable to extend and/or retract relative to the retractable cable reel, and a conduit having a passageway extending along at least a portion of the conduit. The cable can be positioned such that at least a portion of the cable passes through the passageway of the conduit. The distal end of the cable can be coupled to a fastening device.

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.

The invention comprises devices and methods for carrying quantities of materials preferably fluids. The device of the invention is preferably a wearable garment such as, preferably a vest or poncho, with one or more bladders or compartments adapted to hold a fluid. Preferably the garment comprises fluid connections between the bladders. The connections allow for the distributing the load over the carrier, which is preferably a person. The invention is designed to be inexpensive to manufacture, capable of easy manufacture in large numbers, and, if desired, disposable or repurposed. The device significantly enhances the ability of an individual to provide water or other fluids or materials to individuals or groups such as families. Preferably the invention allows for the transport of potable water from a supply point to the point of end use with minimal or no discomfort to the wearer. Preferably the invention supports the heating and/or cooling of the fluid or other applications, including use of building materials.

A wetsuit is provided which comprises (a) a first central region comprising a first material and having a first thickness; and (b) a second lateral region comprising a second material and having a second thickness. The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

A wetsuit (101) is provided which comprises (a) a first central region (125, 127) comprising a first material and having a first thickness; and (b) a second lateral region comprising a second material and having a second thickness. The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

A harness for securely wearing a hydration scarf while walking, jogging, or running, and for extending the time that a beverage in the hydration scarf remains cool. The harness has straps that secure the hydration scarf to the person wearing it, even while engaged in vigorous activity. The harness also has an insulating layer and an insulating sleeve that substantially slow the transfer of body heat into the hydration scarf. Pockets can be included for holding freezer packs in direct contact with the hydration scarf to chill the beverage. The combined effect of the insulating elements that limit heat flow from the wearer's body to the beverage, and the freezer packs that pull heat out of the beverage, is to keep the beverage at a temperature which is cooler than room temperature, and therefore more refreshing and better tasting than a beverage at room temperature.

The present invention relates to a collar formed along the neck circumference of a top, and more particularly, to a water container storage collar that is formed with a storage part having a hollow collar, provided with a heat insulating material inside the storage part to constantly maintain the temperature of a beverage contained in a water container, and formed with a water intake pipe extending from the water container to drink water without using a hand.

A garment configured for retaining a beverage container and for use on the lower body of a user. The garment includes a pocket coupled to the garment, and a tab coupled to the garment at first and second locations. The pocket includes a lower closed edge, first and second closed side edges and an open upper edge. The pocket is sized to removably receive and retain the beverage container. The first and second locations are spaced apart from each other to define an unattached region of the tab between the first and second locations. The unattached region configured for facilitating the opening of the beverage container by the user.
