Anyone whose work, leisure activities or medical conditions cause the body to rise to uncomfortable temperatures and/or affect performance could benefit from a StaCool Vest.

Heat stress occurs when the body's reaction to the environment causes its core temperature to rise above safe limits. This can result in a racing heart, profuse sweating, dizziness, reduced energy and slowed reaction times. This reduces safety, decreases efficiency and lowers productivity.

ThermoPaks are completely non-toxic and non-flammable. They are FDA approved and safe enough to be used in direct contact with food. Unlike phase-change material that must be washed off immediately when it contacts skin, ThermoPaks offer 100 percent safety and peace of mind.

Cooling time depends upon the ambient temperature and the amount of BTU's being produced by the wearer. In most situations, the vests provide more than two hours of cooling per ThermoPak set. By keeping spare ThermoPaks in a cooler, users can easily keep core body temperatures at comfortable levels for many hours.

When you are the first to develop a great product, like the body cooling vest, copycats are soon to follow. But make no mistake, the StaCool Under Vest is the original cooling vest. With a front-zippered design, the StaCool vest is also the most streamlined vest in the market today.

Other manufacturers have plagiarized our concept and tried to match our success, but they have failed to put in the research and development hours that we have. The StaCool Under Vest is not an accidental success or product of chance. It is the result of countless hours of engineering, development and testing.

We receive numerous calls each year from people that have purchased these “budget” vests and even more expensive ones. The calls include complaints of cooling vests that are too heavy, vests that soak you with water, and vests that simply don't work.

Another common complaint from budget vest users is that the vests are too bulky, industrial looking and embarrassing to wear in public.


The StaCool Under Vest avoids all of these problems, putting it in a higher quality class. We have designed and manufactured a cooling vest that is effective, comfortable, form fitting and lightweight. This allows you to wear it anytime you want, and in any situation.

The StaCool Under Vest has also been developed with your safety in mind. The cooling ThermoPaks are non-flammable, non-toxic, FDA approved and safe enough to be used in direct contact with food.

We recommend hand washing the StaCool Under Vest in mild detergent and warm water, and hanging it to dry. Topical cleaners, disinfectants and other germicidal cleaners that are fabric-safe, like those used by hospitals, are also acceptable.
