Stay Cool and Comfortable with INUTEQ’s Phase Change Cooling Vests

When it comes to staying safe, cool, in control and comfortable in warm to hot environments or circumstances, choosing the right cooling gear is essential. Whether you're working in extreme heat, high humidity, training in- or outdoors, managing a medical condition or any other situation that affects your ability to regulate body temperature at a precise temperature, a phase change cooling vest can make a world of difference. At INUTEQ, we specialize in cutting-edge personal cooling technologies - and our phase change cooling vests are at the forefront of performance and innovation.

What is a Phase Change Cooling Vest?

A phase change cooling vest uses advanced phase change materials (PCMs) to absorb and store heat, thereby keeping your body temperature in check. These vests contain 100% biobased and biodegradable PCM, which solidify at a specific temperature,  predefined at 6,5°C / 44°F, 15C/59F, 21C/70F, 24C/74F and 29C/84F). When worn, the PCM absorbs excess body heat and maintains a constant cooling temperature as it changes from solid to liquid.

Phase Change material (PCM) works just like water and ice, but at a different temperature. Like water it is fluid when at or above its designated temperature (which can be 6.5C, 15C, 21C, 24C or 29C) and like ice it is solid when kept some degrees under its designated temperature for some time. When the PCM is solid it can be applied for personal cooling by wearing it close to the body. Ice is too cold for this (it will burn your skin) and will last too short. PCM at 21C is the closest to the natural comfortable temperature, so it is perfect in most circumstances.

Depending on your situation and necessity your choice of the PCM temperature will make a big difference:

• the lower the temperature of the PCM the quicker you will cool down
• the lower the temperature of the PCM the shorter the cooling will last
• the highest temperature of the PCM will last the longest but will still cool you down

The PCM will work until it is completely fluid again. Recharging will need a temperature at least 3 degrees below the PCM designated temperature (i.e. 18C for th2 21C PCM), but will charge faster at lower temperatures.

Unlike evaporative cooling garments, which rely on air flow and humidity, phase change cooling vests offer consistent, reliable cooling regardless of external conditions. This makes them ideal for humid climates, indoor environments, and use under protective clothing like hazmat suits, military gear, or firefighter uniforms.

What types of Phase Change Cooling Vests are there?

Our PCM cooling vests are available in two styles: one that uses removable PCM inserts, and the PCM CoolOver, which has fixed, built-in PCM-modules.

The cooling vests with inserts are specially designed vests with pockets where PCM inserts can be placed. This very modular approach offers great flexibility of replacing used PCM inserts or change the vest to offer different cooling temperatures.

The PCM CoolOvers are vests with fixed, not replaceable PCM-modules.

Why Choose INUTEQ Phase Change Cooling Vests?

At INUTEQ, we are global leaders in personal cooling solutions. Our mission is to improve human performance and safety by developing the most effective and durable cooling technologies available. Here’s why INUTEQ phase change vests stand out:

• Advanced Cooling Technology: INUTEQ’s PCM inserts are engineered with non-toxic, 100% biobased and biodegradable materials that offer maximum thermal regulation without compromising comfort or mobility. Our cooling vests provide a steady temperature for a duration of 1 to 4 hours, depending on the PCM temperature you choose. Both the standard inserts and the CoolOvers are rechargeable in a refrigerator.
• INUTEQ PCM vests are available in different steady temperatures  6,5°C / 44°F, 15C/59F, 21C/70F, 24C/74F and 29C/84F. The inserts are color coded for easy recognition.
• Comfortable and Lightweight Design: Ergonomically designed for long wear, even under heavy gear. Durable and robust materials with evenly distributed weight to avoid strain. Adjustable straps ensure a snug, customized fit.
• Versatile Applications: Used across many sectors:
  • Industrial work (construction, mining, oil & gas)
  • Military and tactical operations
  • First responders and firefighters
  • Medics and patients in medical conditions such as MS (Multiple Sclerosis)
  • Athletes and sports professionals
  • Event and festival staff
  • Gamers
  • Motorcyclists and outdoor adventurers
