orget clunky battery packs and buzzing mini-fans that merely push lukewarm air under your clothes during a summer heatwave. The hissy cooling jacket pairs swappable CO₂ cartridges with technical apparel to tackle extreme urban heat, swapping traditional electronics for compressed gas.
The system relies on liquid carbon dioxide stored under high pressure. When released inside the garment, the high-pressure liquid CO₂ vaporizes instantly to generate a brisk, ice-cold airflow across the torso. The design also repurposes captured industrial CO₂ as its cooling medium, turning waste emissions into personal temperature relief. Reloading the setup on the go does not require fiddling with screws or latches: an intuitive magnetic lock draws the cartridge into position and automatically engages the locking structure without tangling you in wires or lugging dead weight.
While the concept sidesteps heavy power banks, it bluntly trades battery charging for a recurring supply chain of consumable gas canisters. If you plan to spend hours under blistering sun, you will need a steady supply of cartridges rattling in your bag. It is an unapologetically experimental take on personal climate control, and we will see whether carrying pressurized gas beats standard wearable air conditioners once real-world street testing begins.
