Revolutionary Co₂ Cooling Jacket System for Hot Cities
The Hissy co₂ cooling jacket is a groundbreaking solution designed to combat soaring urban temperatures. Unlike traditional portable cooling devices that rely on bulky batteries and fans, this jacket uses a lightweight CO₂ cartridge that integrates into the sleeve through magnetic docking. As the cartridge activates, high-pressure liquid carbon dioxide vaporizes, creating a dramatic cooling airflow of approximately -30°C.

Advanced Design for Effective Airflow with the Cooling Jacket
The jacket’s innovative design features an internal Air Path to effectively distribute the cooling effect. This ergonomic spiral pattern, guided by thermal mapping and heat-distribution experiments, ensures that airflow is precisely directed towards the body’s key heat-generating areas. By maintaining a consistent cooling pressure from the cartridge through the system, the cooling apparel provides controlled thermal comfort.

Secure and Sustainable Cooling Mechanism
The CO₂ cartridge is ingeniously secured with a magnetic docking system, ensuring a snug fit without traditional screw threads. This allows for easy insertion and removal while keeping the cartridge stable during use. Additionally, the garment includes a chest pocket for extra cartridges, making replacements simple and accessible.

The use of recycled CO₂ from industrial processes underscores Hissy’s commitment to sustainability. After use, cartridges are collected, inspected, refilled, and returned to circulation, thus minimizing carbon impact.
