Why Cooling?
Extreme heat is no longer a seasonal event. As the planet gets hotter every year, outdoor workers are the first to suffer.
Heat wave days per year
Annual heatstroke patients
Outdoor workers (millions)
Climate Crisis
Heat wave days have doubled in the past decade. Urban heat islands combined with climate change are rapidly deteriorating outdoor working conditions.
Human Vulnerability
Human thermoregulation has limits. Above 38°C, concentration drops by 50% and heatstroke risk increases exponentially.
Solution Gap
Existing cooling products fail to deliver performance, convenience, and portability together. Field workers deserve a real solution.
