The shift

## Cool the worker. Not the building.

A century of cooling was built for spaces, not people.
Until now.

01

### Contact cooling where it counts.

Active cooling sits against the core, drawing heat off critical organs as it builds. Not dependent on shade, humidity, or environment.

02

### Works with the PPE they already wear.

Under 3 lbs. Works with a fall-arrest harness. A full shift on one battery swap. Nothing extra to carry.

The stakes

## Every hot day, you choose: production or safety.

$50K–$200K+
Single heat-incident cost, before litigation

30–50%
Output drop on peak-heat days

36M+
Heat-exposed US workers
