"At the heart of the Entropy Vest lives a web of tubes that resemble the veins of a strange futuristic cyborg animal. Filled with a secretive liquid phase-change material, the vest wears cool until you literally flip a switch. (Phase-change material can store or release energy, a process that happens as it changes between two fundamental states of matter.) Once activated in the Entropy Vest, the liquid begins to change its structure, releasing heat as the reaction progresses through the vest’s vascular system."
