COOLING PACKET - COOLSHIRT SYSTEMS | COOLSHIRT SYSTEMS · moisture by reacting to your sweat and pulling it away from the skin. **Some other products can cause more chilling than

PCM ELITEMade of Lightweight Industrial Grade ventilated nylon, this vest is an extremely breathable garment and can

be worn for hours to help the wearer feel more comfortable.

Sewn with 6 pockets on the inside to hold our Comfort Zone packs, the vest weighs only four

pounds. These innovative packets help keep the microclimate temperature between the skin and the

vest at a comfortable range for up to three hours.

Available in both ventilated nylon and flame retardant mesh

COOLING PACKETThese flexible and lightweight packs are filled with Outlast® technology. This patented, heat managing technology helps keep the microclimate temperature between the wearer and the vest in a more constant & safe comfort zone.

HOW DOES THE TECHNOLOGY WORK?Outlast® is the heat management technology originally developed for NASA that enables our Comfort Zone Packs to absorb, store and release heat. It proactively responds to changes in skin temperature to manage heat and reduce moisture for everyday comfort.

This remarkable technology enhances the product by providing the benefit of proactive heat management. It’s important to remember that it is not wicking technology - which manages moisture by reacting to your sweat and pulling it away from the skin. **Some other products can cause more chilling than the body is intended to be exposed to for long periods.

How the body cools

About 90 percent of the body’s heat is produced in the torso area by the major organs and muscle groups. The amount of heat generated is increased as the body works harder. In order to maintain a constant core temperature, the body must either give up or retain this heat as necessary. How this is accomplished depends greatly on the ambient temperature and humidity around you.

Convective body cooling

Under normal conditions (60° to 80° F ambient temperature), the circulatory system carries core heat toward the skin’s surface. Since heat always travels from hot to cold, rather than from cold to hot, the body heat is carried away as the cooler outside air passes over the skin. This process is known as convective cooling, since the heat is removed by the movement of air. Evaporative body cooling.

As the temperature outside begins to rise, the difference between the normal skin temperature (90° F) and the ambient temperature narrows. This difference is known as the delta T. As the ambient temperature rises above 80° F, the delta T is not great enough to allow the body’s internal heat to flow away from the body by convection.

Instead, the body reacts by cooling itself through a process known as evaporative cooling. When water fluid is exposed to warm, dry air, it will evaporate into water vapor. This change of state is called a phase change and it produces a tremendous cooling effect. The body creates this phase change by secreting perspiration from our sweat glands to the surface of the skin. When the air surrounding the skin is warm and dry, this is an extremely efficient process. But as the humidity rises, perspiration can no longer evaporate into water vapor, as the air is already saturated. This is a dangerous condition, since the body has no other natural mechanism.

Is the product safe?

An expert team continuously tests every product and the technology itself, Outlast® technology meets Oeko-Tex testing for safety which is synonymous for the highest standards in safety.

Does the technology work?

Yes. The American Society for Testing has established a standard test procedure (ASTM D7024) to measure the effects of changing temperature and a fabric’s ability to absorb, store and release energy.

Founded in 1898, ASTM International is one of the largest standards development organizations in the world.

“Patented technology was originally developed for use in space gloves to protect against extreme temperature fluctuations & is a shining example of how mankind benefits from the space exploration, often and unexpected ways.”

-Kevin C. Cook, vice president of marketing and communications for the Space Foundation.

Unlike canvas vests, our lightweight ventilated nylon outer vest allows for additional cooling properties. Perfect for use by radiologists, sterile processing personnel, circulators & more!.
