Battery-powered cooling vest for industrial workers

One vest. Every crew that works in the heat. Cooling that finally keeps up with the work.

ClemaCore is a solid-state cooling vest for construction, oil and gas, utilities, manufacturing, logistics, and military crews. Worn under existing PPE. Under 2 lbs. A full shift on one battery swap. Replaces ice, PCM, and evaporative vests.

The shift

Cool the worker.
Not the building.

A century of cooling was built for rooms.
The work was never inside.

How it works

Cooling that goes where the work goes.

01

Cools the body, not the air.

Active cooling sits against the core and draws heat away the moment it builds. Not dependent on shade, humidity, or environment.

02

Built into the gear they already wear.

Under 2 lbs. Fits beneath hi-vis, FR, and fall-arrest. A full shift on one battery swap. Nothing extra to carry.

Built for the crews that work in real heat.

The stakes

Every hot day, you’re choosing:
slow the crew, or risk one.

Heat illness is a liability problem, not a wellness one. One heat incident costs $50K–$200K+ before litigation. Clema costs less than a single claim.

$50K–$200K+ Single heat-incident cost, before litigation
30–50% Output drop on peak-heat days
36M+ Heat-exposed US workers
