Cooling for inclement conditions.

Palomino Series — the wearable cooling vest

Cooling sized to the thermal load each body carries — for heat-exposed workers, tactical and defense personnel, athletes and the adaptive, and anyone requiring thermoregulation assistance.

The Science of Cool

Three tiers of cooling, mapped to the body.

Perceived cooling, vascular cooling, and progressive zone targeting — three tiers of thermal coverage designed to regulate core temperature and dissipate heat stress,12 mapped to the body and driven by the platform. Each tier activates a new vascular region — peri-thoracic, axillary, cervical — escalating thermal coverage without adding bulk or complexity.

Temp°IQ™ cooling zones mapped to the body — front and rear, showing the three escalating thermal tiers
1

RoutineTier 1

Peri-thoracic, upper chest & lower abdomen.

2

High DemandTier 2

Addition of the axillary zone.

3

SpecializedTier 3

Addition of the cervical zone.

Audience: heat-exposed workers, tactical/defense, athletes (incl. adaptive), and people with unreliable thermoregulation.

The four segments

Occupational

Workers in heat — welding, foundry, forklift, warehouse.

Tactical

Government / defense; body armor and field gear. Separated from Occupational for its distinct buyer and compliance path.

Athletic & Adaptive

Adaptive golf, Paralympic, recreational sport.

Medical Thermoregulation

MS, dysautonomia, spinal cord injury; daily-life heat vulnerability.

A cross-cutting filter

PPE level A–D

Protective equipment runs from Level D (minimal / surgical / light splash) to Level A (full hazmat encapsulation). It appears across Occupational, Tactical, and Medical, so it is an input to the calculator, not a segment. Encapsulation is often the single biggest driver of cooling need.34

What we measure

  • Heat removed and cooling efficiency (the calorimeter) — how cold the device holds against a real heat load.
  • The steadiness signal — a settled versus drifting / “hunting” cooling demand — as a read on whether regulation is keeping up.
  • Perceived temperature versus tolerance, and autonomic load (HRV); each against the individual’s own baseline.

Engage — the Cooling Calculator

One step into Heat Safety.

What goes in

Segment, activity (metabolic load), and PPE level (A–D).

The occupational view breaks the need into five variables — the work, the place, the gear, duration and mobility, and the form factor: cooling embedded in worn gear, whether vest, neck, limb brace, boot, or PPE liner.

What comes out

An off-the-shelf recommendation — the Palomino V1.

A portable custom solution, sized to the role.

Or a full custom build — “tell us your heat problem,” routed straight to the team.

Advance

Use compounds into understanding.

Calorimeter validation plus occupational data → new form factors, better cooling in the gear people already wear. Today the tiers are indicative. Live heat-removed data turns each scenario into a measured watt target.

Heat Safety white paper

The science of measured, personalized cooling.

Agreed outline from the Engagement Portal.

Does measured cooling reduce heat burden and protect function for people whose thermoregulation is unreliable — and improve safety and performance for heat-exposed workers and adaptive athletes? Observational and within-subject; consumer device (non-FDA).

Draft outline · not yet published
Regulatory note. Consumer cooling-vest framing is non-FDA. Claims are kept appropriate to this context.
Open decisions. One shared Cooling Calculator with a segment selector vs. a tool per segment (recommendation: one shared). Does Tactical / defense become its own top-level audience later?
