A closure system is provided. The closure system comprises an outer panel comprising an inner surface having a plurality of connecting members. An inner panel is provided comprising an outer surface having a plurality of connecting members, and an insertion panel configured for engagement with the outer panel and the inner panel. The insertion panel comprises an interior surface and an exterior surface where each surface includes a plurality of connecting members. The inner surface of the outer panel engages with the exterior surface of the insertion panel, and the outer surface of the inner panel engages with the interior surface of the insertion panel so as to seal the insertion panel with the outer and inner panels. Methods of use are also disclosed.

A technique for delivering heating or cooling to a diver includes a suit that includes a water-impermeable outer layer, an insulating layer having a channel extending along a diver-facing surface thereof, and a tube disposed within the channel of the insulating layer. The tube is constructed and arranged for carrying heat-transfer fluid to a proximity of the diver's skin.

A waterproof seal includes a flexible annular tube formed by an inner layer and an outer layer of a garment and surrounding a passage through which a human appendage is intended to protrude. A first cord is positioned in a cavity defined by the annular tube. The first cord has a first end, a second end and extends more than 180 degrees and less than 360 degrees around the passage with the first end and the second end exiting the annular tube. A second cord is positioned in the cavity defined by the annular tube. The second cord has a first end, a second end and extends more than 180 degrees and less than 360 degrees around the passage with the first end and the second end exiting the annular tube. The first cord and the second cord cumulatively cover more than 360 degrees around the passage to provide an effective water seal.

Thermal warming suits for a human occupant of a wet submersible vehicle are described. The thermal warming suits provide a dedicated envelope configured to encase at least a portion of the human occupant in a deformable suit that can be assembled around or donned, as well as be removed, by the occupant or others before or after entry and seating in or on the wet submersible vehicle, while underwater or surfaced. The suits provide a deformable, weight and space (i.e. volume) conscious, collapsible loose fitting perimeter around the occupant. The suits can be used to create a pneumatic barrier around at least a portion of the occupant by using a gas such as air provided from a gas reservoir to force water from the interior of the suit.
