How Texas Cool Vests Mitigate Heat at 65℉
Table of Contents
The Texas Cool Vest is a Personal Cooling System
NASA Developed Technology
Our cooling vests are a personal cooling system that maintains a comfortable 65º F temperature, the optimal temperature for use with the human body as determined by NASA. Our cool packs use a NASA developed and researched phase chase material combined with proprietary plastics with our cool pack inserts to provide the most comfortable and effective heat stress reduction available. That’s why this style of heat mitigation is referred to as a phase change cooling vest.
In the past, the only answer to heat stress was to wear an ice or gel-cooled vest. That meant having a freezing cold pack against your body, damaging your skin and far too cold to be comfortable. To alleviate the discomfort, undergarments were needed as a barrier, defeating the very purpose of the vest.
With phase change material technology, you’ll stay cool and comfortable at a temperature that feels natural to your skin and body. So comfortable, in fact, that our products can be worn directly against your skin for optimal cooling — without the fear of frostbite!
At temperatures lower than 65 degrees, cooling garments can cause vasoconstriction which will confuse your body and not allow it to send the correct signals to protect itself against the heat. In other words, you feel cool but are actually overheating!
Our vests don’t cause vasoconstriction — the Texas Cool Vest works WITH your body to keep core temperature down. Helping you stay cool is work your body doesn’t have to do, saving you energy to be productive and feel better when you get home.
How Our Phase Change Cool Pack Technology Works
A Heat Sync for Your Body
Our cooling packs literally pull heat from the body, like a heat sync, while maintaining a comfortable temperature of 65º F. As the phase change cooling pack absorbs heat from your body, it will begin to phase change from a solid to a liquid.
Because of the constant temperature behavior of phase change material technology, the Cool Packs maintain 65º F during the transition. The transition process can take hours and varies with cool pack size, ambient temperatures, workload, and individual physiology.
The phase change Cooling Packs can be quickly recharged; simply place them in ice water for 20 minutes, or in a conventional freezer for around 60 minutes. A refrigerator will also recharge the packs in a few hours. The packs expand to resist bursting, absorb shock, and maintain mobility. Freeze without any fear of damaging your packs!
Each vest is washable, nonshrink outer shell made from Supplex®, fire-retardant Banox®or Poly Cotton Twill is the first layer of shielding from ambient heat. The shell (vest) is an insulating layer minimizes the absorption of ambient heat by the phase change material cooling packs. The vest will also absorb a large amount of direct sun light hitting your back.
Our cooling vests are designed to hold the Cool Packs securely in place, while absorbing moisture away from the wearer. The Texas Cool Vest is a washable, non-shrink outer shell made from Supplex®, fire-retardant Banox®or Poly Cotton Twill is the first layer of shielding from ambient heat.
OSHA FACT SHEET
HEAT STRESS – PROTECTING WORKERS IN HOT ENVIRONMENTS
Many workers spend some part of their working day in a hot environment. Workers in foundries, laundries, construction projects, delivery drivers, and bakeries — to name a few industries — often face hot conditions which pose increased hazards to safety and health.
Our vests meet and exceed OSHA safety standards. Cooling vests are recommended by the CDC for reducing heat illness in the workforce.

Frequently Asked Questions (FAQs)
Why are Texas Cool Vests better than other phase change based Cooling Vests?
There are four key benefits to Genuine Texas Cool Vest products:
Our genuine Texas Cool Vest “cool packs” will not start leaking or sweating after 6 months like the other PCM vest. This is because of the type of proprietary plastic used to hold the chemicals. Others use cheaper materials to increase their margins. Texas Cool Vest will not compromise on quality, that’s why we only use pure chemicals, and real milspec fabrics and double stitch our vest. We have tens of thousands of vests in service world wide.
Texas Cool Vest phase change material technology Cool Packs operate at a much more comfortable temperature (65 degrees farenheit). Others will claim 50 or 70 degrees PCM. Some are too cold and others are not cold enough, NASA studied this topic and determined 65f is the optimal temperature — that means it won’t cause skin or tissue damage, or cause extreme discomfort like ice packs.
Texas Cool Vest, phase change material technology Cool Packs will be effective for a longer period of time between charges. The reason? The difference in temperature between ambient (surrounding) air and the Cool Pack is much less than the difference in temperature between ambient air and ice. That means more cooling is absorbed by the body and less is lost to the air.
Texas Cool Vest phase change material Cool Packs are cooled to a temperature that is above the dew point. That means they won’t condense or sweat against your body or clothing. Ice and frozen gel packs are below the dew point, so they sweat, making them uncomfortable to wear and adding to the weight of the vest or jacket. Condensation also robs the ice pack of efficiency because condensation creates heat, which is absorbed by the pack, further reducing its efficiency.
How many times can the phase change material cool packs be used?
If the Cool Packs are not punctured or otherwise damaged, they can be recharged thousands of times. The cool packs are rated to last 5 years. If they are stored in a cool dark place and taken care of properly sometimes they will last longer.
How do phase change material technology cool packs compare with evaporative vests?
Phase change material technology Cool Packs provide much greater efficiency and better performance. Evaporative type products, by their nature, retain water, so are always wet and can absorb bacteria. This makes them uncomfortable against your skin. And it means they’ll mildew quickly over time, since they never dry out. Further, evaporative type products can’t operate in high humidity, because the atmosphere is already saturated with water. There is no place for the evaporation to go, so there is no cooling. Phase change material products, on the other hand, are unaffected by humidity.
I have an evaporative water vest, it works sometimes but not others. Why does evaporative vest not work inside my Chemical Suit?
Evaporative vests work like perspiration. The water evaporates and the fabric temperature drops. As the relative humidity increases, there is less room in the air for the water to go, so it slows or stops evaporating. Like when you start to sweat and water beads start to form on your skin. Inside a chemical suit, there is a limited amount of air for the water to evaporate into, also your body is sweating into the same closed atmosphere. The suit will reach 95% Relative Humidity (RH) inside and when you sweat and your boots fill up with water. Our phase change material is 65 degrees. It absorbs the heat, into the cool packs. Unlike Ice packs our cool packs are above dew point and will not sweat or condense water from the air.
Will phase change material Cool Packs reduce body core temperature?
Yes, they will. But keep in mind that our products are worn to maintain core temperature. The purpose of phase change material cooling technology is to maintain a comfortable core temperature and prevent that temperature from increasing. It’s our goal to help you avoid heat stress in the first place.
Isn’t water a phase change material, just like the material in your Cool Packs?
Yes. A phase change occurs whenever matter changes from one form into another. Water can change from a solid (ice) to a liquid, as well as to a vapor. Water changes into a solid at a specific temperature: 32º F. But phase change material Cool Packs change into their solid form at 65º F. Since water changes into its solid form at such a low temperature, it loses more of its cooling ability to ambient (surrounding) temperature. It’s also below the dew point, so it causes condensation as it warms. Further, it’s uncomfortable and requires a freezer to refreeze.
Is the chemical in phase change material cool packs toxic?
The chemical in the phase change material technology cool packs is completely nontoxic, safe, and environmentally friendly. If swallowed, it acts as a laxative. Should the Cool Pack become punctured and bleed onto your skin, it may cause very minor irritation, so it’s important that you scrub with soap and water. If you’d like a Material Safety Data Sheet on this product, please email us and we’ll be happy to send it to you.
Will phase change material Cool Packs cause vasoconstriction?
Not at all. That’s a great benefit of our 65 degree phase change material Cool Packs: They function within a comfortable cooling range that doesn’t allow vasoconstriction of blood vessels, unlike ice. This benefit is important, as nonconstricted blood vessels allow your circulatory system to freely move blood throughout your body, then release heat at the skin surface. With ice, the body is fooled into thinking it’s cold. It reacts by constricting the blood vessels near the skin, limiting the body’s natural cooling system. The heart then works harder, expending extra energy in the chest cavity and creating yet more body heat.
During cardiovascular exercise, will phase change material Cool Packs help slow the heart rate?
Yes. These products will slow the rise in your heart rate so that you can exercise longer and with more intensity, allowing for higher calorie burn. Of course, it’s important that you check with your doctor before undergoing an intensive exercise program.
