GOLD-STANDARD PROTOCOL
Cold Strike™ is engineered around the U.S. military’s proven ice-sheet protocol for exertional heat stroke - the current gold standard for field treatment where cold water immersion is impractical
We don’t replace that protocol; we make it FASTER, SIMPLER, and more CONSISTENT.
Designed by an Army Special Forces medic and an Army logistics officer who treated and moved casualties in some of the harshest environments on earth.

We built the solution we wish we’d had when our own teammates went down from the heat.

Thermal Overwatch was born from lived experience in combat units and training ranges where heat injuries were a constant threat and the tools to treat them were slow, bulky, and improvised.
We knew the science of ice-sheeting worked
So we built Cold Strike™: a purpose-designed system that makes the proven protocol rapid, repeatable, and field-proof.
