All-Day Personal Cooling for Extreme Heat
ChillVest is a wearable personal cooling system that holds cold gel cells against the body and releases the cold steadily over hours — keeping a worker's core temperature in the safe range even at 38°C / 100°F+. When a ColdBank insert warms up, a fresh one swaps in within seconds, so cooling continues all day with no freezer trips mid-shift, no soaked clothing, and no downtime. It fits naturally into existing workwear and safety protocols.

How It Works
Pre-Cool
Place ColdBank cells in a standard freezer or ice cooler for 1–2 hours before the shift.
Wear
Put on the vest. Gel cells sit against the body, separated by a thin comfort fabric layer.
Sustained Cooling
Body heat conducts into the cold gel, which absorbs it evenly — no cold spike, steady release over hours.
Swap, Don't Stop
When a ColdBank warms up, swap in a fresh one in seconds — all-day cooling with no mid-shift freezer trips.
Fluid Circulation
USB-powered DC 5V motor circulates coolant fluid through the vest, ensuring even temperature distribution across all cooling zones.
