Implementations of a clothing article with an integrated thermal regulation system are provided. In some implementation, a clothing article with an integrated thermal regulation system may be configured to heat a portion of a wearer's body by transferring heat from a warmer first region of the body (e.g., the calf portion of the leg or wrist portion of the arm) to a cooler second region (e.g., the plantar side of the toes or the dorsal side of the fingers). The transfer of heat is facilitated by a thermally conductive fluid that flows between a first thermal transfer bag in heat exchange contact with the warmer first region of the wearer's body and a second thermal transfer bag that is in heat exchange contact with the cooler second region, the thermal transfer bags being held in position by the clothing article into which they have been integrated.

Disclosed is a magnetic connector comprising a body having a mounting cavity, the body comprising a PCB received in the mounting cavity, a first conductive terminal soldered to one side of the PCB and extending toward an opening of the mounting cavity, a first magnet disposed along the periphery of the PCB and on the same side as the first conductive terminal. The body further has a first anti-off device which is formed with an insulating bushing enclosing the first conductive terminal or the first magnet. The magnetic connector provided by the present invention has advantages that the connection is more stable and more durable, that the service life is longer, and that a certain degree of solid connection can be maintained even if a part of the anti-off device has failed, which is of a good fault tolerance.
