These vests have been constructed with a high level of durability in mind specifically for use in demanding environments. Vests include a convenient zipper closure and a comfortable v-neck style. Adjustable hook-and-loop fasteners at the girth and shoulders allow for a personalized fit.



This vest is made to keep you cool and comfortable even when the outside temperature is high and the working environment is warm. Because of the innovative construction of this ice vest, you can quickly reduce the warmth of your core by simply slipping it on and off. This ultra-thin cooling vest is designed to maintain its flexibility at any temperature, providing the highest possible level of comfort.

Ergodyne Chill-Its


This cooling vest is designed to be between 30 and 60 percent lower in weight than similar products on the market, and it helps keep workers cooler, safer, and more productive. After activation, the 100% biodegradable phase change cooling compound in it keeps the temperature at 59 degrees Fahrenheit (15 degrees Celsius) for up to two hours. The hook-and-loop closures that are adjustable at the waist of the vest provide a tailored fit that is suitable for a variety of body types.

Understanding Phase Change Materials (PCMs)

Before diving into the specifics of phase change cooling vests, it is essential to grasp the concept of phase change materials. PCMs are substances that can absorb, store, and release thermal energy during the process of phase transition, typically from solid to liquid and vice versa. This remarkable property allows PCMs to maintain a constant temperature during phase change, providing a prolonged cooling effect when applied to the body.

How Phase Change Cooling Vests Work

Phase change cooling vests utilize PCMs in their design to create a cooling effect. The vests are constructed with pockets or compartments filled with specially formulated PCMs that have a melting point close to the desired cooling temperature. These PCMs are typically encapsulated in a flexible and durable material, allowing for ease of use and comfort.

When exposed to excessive heat, the PCMs absorb the heat from the body, transitioning from a solid to a liquid state. This phase change process keeps the body temperature within a comfortable range, preventing overheating and allowing the wearer to stay cool for an extended period.

Key Features of Phase Change Cooling Vests

  • Long-lasting Cooling: Phase change cooling vests provide a significantly longer cooling duration compared to traditional cooling methods. The slow and controlled release of thermal energy from the PCMs ensures a continuous cooling effect for several hours, making them ideal for extended periods of outdoor activity or work in high-temperature environments.
  • Customizable Cooling Temperatures: Depending on the specific application and individual needs, phase change cooling vests offer the flexibility to choose from a range of melting temperatures for the PCMs. This allows users to tailor the cooling effect to their preferences, ensuring optimal comfort in various conditions.
  • Lightweight and Flexible Design: Modern phase change cooling vests are designed to be lightweight and flexible, enabling freedom of movement and minimizing any hindrance to the wearer. The ergonomic design ensures that the vest conforms to the body, providing a snug fit and maximum cooling efficiency.

Benefits and Applications

  • Heat Stress Prevention: Heat-related illnesses such as heat exhaustion and heatstroke pose significant risks in various industries, including construction, agriculture, and manufacturing. Phase change cooling vests offer an effective way to regulate body temperature, reducing the risk of heat stress and enhancing worker safety.
  • Sports and Outdoor Activities: From athletes to outdoor enthusiasts, phase change cooling vests are highly valued for their ability to provide long-lasting cooling during intense physical activities. Whether it’s running, hiking, or playing team sports, these vests can help maintain optimal body temperature, improving performance and reducing the risk of heat-related injuries.
  • Medical Applications: Phase change cooling vests are widely used in medical settings, especially during surgeries or procedures where patients may experience elevated body temperatures. By regulating body heat, these vests contribute to patient comfort, post-operative recovery, and the prevention of complications.
  • Military and First Responders: Military personnel, firefighters, and first responders often face extreme heat conditions while carrying out their duties. Phase change cooling vests offer a practical solution to manage body temperature, ensuring the well-being and performance of these professionals in high-stress situations. These vests can help minimize the risk of heat-related injuries and improve the overall effectiveness of critical operations.
  • Personal Use: Phase change cooling vests are not limited to specific industries or professions. They are also gaining popularity among individuals who seek relief from hot weather or those with medical conditions that make them more susceptible to heat. Whether it’s gardening, outdoor events, or simply enjoying leisure time outdoors, these vests provide a reliable and convenient cooling solution.


Phase change cooling vests have revolutionized the way we combat heat stress and maintain comfort in high-temperature environments. By harnessing the power of phase change materials, these vests offer long-lasting and customizable cooling effects, making them an indispensable tool for a wide range of applications.

From industrial workers and athletes to medical professionals and outdoor enthusiasts, the benefits of phase change cooling vests extend to various sectors, enhancing safety, performance, and overall well-being.

As we continue to face the challenges of rising temperatures and heatwaves, phase change cooling vests have emerged as a practical and efficient solution to beat the heat.
