High-performing liquid-cooled apparel

A wearable cooling system, the system comprising:

• a wearable garment comprising a fabric portion and a first plurality of tubing secured to the fabric portion so as to contact a user's skin while the user is wearing the garment;
• at least one cartridge comprising a second plurality of tubing and a phase change material, wherein the phase change material is configured to be in thermal contact with a coolant passing through the second plurality of tubing;
• and
• one or more connectors for connecting the first plurality of tubing with the second plurality of tubing,
• wherein the first plurality of tubing is composed of a thermally conductive material,
• wherein the first plurality of tubing comprises one or more serpentine arrangements, and
• wherein the one or more serpentine arrangements comprises a nested sinusoidal arrangement.

A method for thermoregulation of a user using a wearable apparel, the method comprising:

• wearing a garment comprising a four-way stretch fabric and a first plurality of tubing secured to the four-way stretch fabric so as to contact a user's skin while the user is wearing the garment;
• flowing a coolant through the first plurality of tubing;
• connecting at least a portion of the first plurality of tubing to a second plurality of tubing in a cartridge, wherein the cartridge comprises a phase change material;
• and
• passing the coolant through the phase change material in the cartridge and back to the first plurality of tubing,
• wherein the first plurality of tubing comprises one or more base polymers and one or more additives that increase a thermal conductivity of the one or more base polymers,
• wherein the first plurality of tubing comprises one or more serpentine arrangements, and
• wherein the one or more serpentine arrangements comprises a nested sinusoidal arrangement.
