CoolOver-X 21C Biobased PCM Cooling Vest

CoolOver-X 21°C Biobased PCM — INUTEQ (Made in the Netherlands)
Developed with the Bad Homburg Firefighter Department, this cooling vest is built for extreme heat and designed to be worn under protective clothing. It delivers a stable 21°C / 70°F cooling temperature using INUTEQ-PAC® biobased PCM (USDA 100% biobased, REACH registered).

Key Features

• Constant 21°C / 70°F cooling

• Built for firefighting, industrial work, hazmat suits, military gear, medical environments, and hospital staff working in high-heat or PPE-intensive conditions

• One-size-fits-most with adjustable Velcro belt

• Tough construction, universal fit, easy to disinfect

• Fast activation in ice water, freezer, fridge, or any environment 3°C below the PCM temperature

• Effective cooling time: up to 2.5–3 hours

• Weight: 1.3 kg / 2.65 lb

• Max chest circumference: 120 cm / 42 in

How It Works

PCM cells solidify when chilled and absorb heat as they melt back to liquid, delivering controlled, reliable cooling.

• Solid = active

• Liquid = deactivated

Cell layout:

• Front: 4 × 4 cells

• Back: 4 × 5 cells

Usage Tips

• Do not wear directly on skin. Add a layer over it to extend cooling time.

• Always cover the vest — leaving it exposed reduces duration.

• Works under PPE, hazmat/airtight suits, mascot suits, firefighting gear, and medical PPE.

Activation

• Cool in ice water, freezer, fridge, or any environment at least 3°C below its set temperature.

• Keep the vest flat or hang it in a cool room.

• Avoid stacking; rotate if you must stack.

• Surface may feel colder at first — it stabilises at 21°C.

• Activates in rooms under 18°C.

Transport

Use a cool bag or cooling backpack to keep the vest activated on the way to the worksite or hospital.

Cleaning

Wipe clean with warm water or disinfectant.
