Abstract: An outdoor activity suit includes a body having a front portion, a back portion, opposed sides where the front portion connects to the back portion, a neck receiving portion, an arms receiving portion and a legs receiving portion. The front portion, the neck receiving portion and the legs receiving portion of the body form a first component of the body. The back portion and the arms receiving portion form a second component of the body. An endless loop zipper connects the first component and the second component such that the second component is selectively removable from the first component.

Abstract: A personal flotation device is formed with a neck opening defined by a plurality of discrete lobes projecting in toward the inside of said neck opening and including a chin lobe that is positioned to engage the underside of the chin of a user when device is in operative position on said user and inhibit removal of said device over the head of the user. The chin lobe is spaced from adjacent portions of adjacent said lobes to provide spaces therebetween to facilitate donning and doffing of said device when said chin is aligned with one of the spaces. The device is also preferably provided with cover panels that releasably connect together around their peripheries so that the edges of the bladder contained between the cover panels may be folded and retained in folded position when the sides of the over panels are connected.

Abstract: A buoyancy device has a rear buoyancy area interconnected to a pair of lateral under arm buoyancy areas by a pair of front buoyancy areas, and combining to form a simulated W-shape when viewed in a plan view. The provision of the lateral or underarm buoyancy areas function to hold the user more upright and normally higher above the level of the water when in use.

Abstract: A pressure-applying garment particularly suited for locating and applying pressure to transmitters is formed by a main inflatable bladder inflated to first pressure to press its inner wall toward a wearer and conform the inner wall to contours of said wearer and to apply the desired pressure between the wearer and a transmitter interposed between the main bladder and the wearer. A plurality of auxiliary inflatable bladders positioned relative to the main bladder and oriented to having their inner walls facing toward said wearer. The auxiliary bladders are provided with separate inflating systems so that at least some of said auxiliary bladders are inflated to a selected pressure different from (higher than) the first pressure to deform inner wall of its auxiliary bladder to conform with and press towards adjacent portions of said wearer and preferably to apply the desired pressure between the wearer and a transmitter interposed between the auxiliary bladder and the wearer.

Abstract: An anti-G pressure garment system incorporates an inflatable pressure bladder covering portions of the wearer's body. The bladder is provided with an area made of a first material formed by a flexible air and liquid impermeable, vapor permeable, micro-porous material that facilitates the passage of water vapor therethrough whereby pressurized gas will be retained by the said bladder and water vapor adjacent said inside layer will pass through said material into the interior of the bladder. The bladder also includes a second area made of liquid impermeable, air and water vapor permeable material so that the second area permits a preselected amount of controlled leakage from the bladder to the wearer while maintaining adequate pressure in the bladder.

Abstract: An inflatable device having a safety system provided by having at least two separate and distinct independently inflatable bladders contained within the outer shell of the device. Each of the bladders is designed when fully inflated to fully inflate the shell, but during use one of the bladders is not fully inflated and has a projected area of no greater than 50% of the projected area of the inflated shell.

Abstract: An easy access immersion suit, in which the zippered opening starts at the crotch, runs diagonally up across and around the hip, diagonally across the back and ending at the underarm opposite the previous referred to hip.

Abstract: An enhanced personal cooling garment has an inner layer and outer layer that define a confined space or bladder therebetween for containing liquid water. The inner and outer layer are thin materials that are impermeable to both air and liquid water yet permeable to water vapour. The garment is worn in a manner such that the innermost layer is in direct contact with the wearer's skin. The liquid water between the layers diffuses as vapour through the outer layer; it removes latent heat required for evaporation hence provides cooling to the human body. As both layers of the garment are permeable to water vapour, sweat produced by the wearer can diffuse through the innermost layer, where it will then condense into liquid. When worn beneath an air-cooling garment that distributes cool; dry air over the body, the rate of evaporation increases, resulting in even greater enhancement of cooling of the wearer.
