A cooling vest is a special garment designed to regulate body temperature using advanced materials and cooling methods.
They differ significantly from regular cooling clothing, both in design and functionality. Originally intended for industry, they are now used everywhere.
The cooling vest is thus a functional garment built to cool the body in warm environments.
It works through water absorption and evaporative cooling – the material absorbs moisture and releases it slowly through evaporation.
They are made from lightweight, airy fabrics that allow air to pass through while retaining the cooling effect. Often, moisture-wicking fibers and sometimes cooling gel technology activated with water are used.
The whole concept is based on evaporation drawing heat away from the body, so the temperature drops when you work or spend time in the heat.
Cooling vests are not like regular summer clothing – this is about active cooling rather than just allowing air to circulate.
While loose clothing mainly ventilates, cooling vests use materials that actively absorb and release heat.
Compared to cooling towels or cooling scarves, the vest covers a larger area of the body and retains the cold longer. Additionally, your hands are free, which is quite crucial on the job.
Regular work clothing is primarily designed for protection and durability, but cooling vests are specialized for temperature control. This makes them especially useful when overheating is a threat.
Cooling vests first appeared for people working in really tough environments, such as steel mills and chemical industries in the 1970s.
Over time, new technologies like phase change materials and microfiber emerged, making the vests both more effective and comfortable.
Today, they are used in everything from construction to logistics. Variants for different seasons and work environments have also emerged – it's quite interesting how quickly the development has progressed, actually.
There are several technical solutions, but the basic idea is to lower body temperature through evaporation, air circulation, or phase change.
The choice of materials and how the vest is constructed determines how well it transports heat away.
Most cooling vests are based on evaporative cooling. The water in the fabric evaporates and takes heat away from the body.
When water changes from liquid to vapor, energy is required, and this energy is drawn from the skin – that's how the cooling occurs.
Some cooling vests have built-in fans powered by small batteries. The fans enhance airflow and help sweat evaporate faster.
There are also models with phase change technology. These use materials that melt at a certain temperature and store heat, allowing them to maintain a consistent coolness for a long time.
Polypropylene plastic is popular in cooling vests that need to perform really well – it can transport significantly more moisture than regular polyester and dries faster.
Other materials commonly used include:
Techniques like TEMPTECH elements are based on special fibers that absorb heat from the body. The elasticity of the material ensures that the vest fits snugly against the skin for optimal effect.
Cooling effect means that the vest helps the body not to get warmer by enhancing natural cooling.
It ensures that sweat evaporates faster and keeps the skin dry.
Refrigerating effect is a bit more advanced – it actively lowers body temperature, often using ice or gel that absorbs a lot of heat.
Cooling vests are suitable when you are moving a lot and need cooling for an extended period. Refrigerating models are more used for medical needs or acute heat stress, where quick action is necessary.
Cooling vests have several clear advantages. They actively cool the body and relieve the body's own cooling system.
It's about increasing comfort, reducing risks, and sometimes even helping with medical conditions.
Cooling vests are an effective way to keep body temperature at a good level when it's hot.
They use various techniques to draw away excess heat, and there are several variants:
In hot industrial environments, cooling vests are often invaluable. They help the body cope with heat better than it otherwise would.
Heat stress is a real threat in workplaces where temperatures are high.
Cooling vests help the body stay cool and reduce the risk of:
People who use cooling vests tend to feel less fatigued and less irritable during long days. This can actually make the work environment safer, as fatigue often leads to mistakes.
They are especially useful for those working in construction, industry, or other heavy professions where heat is a constant challenge.
Cooling vests can also be prescribed as aids for individuals with medical issues where temperature regulation is difficult.
MS is perhaps the most well-known example where cooling vests are used to alleviate symptoms.
Medical uses include:
To get a cooling vest prescribed, it often requires that it actually helps the person cope better in daily life. Usage is often followed up after a few months to see if it makes a difference.
For many with MS, a cooling vest can be the difference between being able to participate in activities or being stuck at home when it's hot.
Cooling vests improve the body's ability to recover from physical exertion by reducing the metabolic load from temperature regulation. This frees up energy for other bodily functions.
Professional athletes use cooling vests both before and after exertion. Pre-cooling prepares the body for intense activity.
Post-cooling, in turn, can accelerate the recovery process.
Physiological benefits include:
Workers in physically demanding jobs experience less fatigue when using cooling vests. They can often work longer without risking overheating or exhaustion.

In industry, cooling vests are sometimes crucial for both safety and productivity. Construction workers, welders, and factory employees use them to prevent heat stress during long days.
Industrial cooling vests must withstand tough conditions. They are made from materials like polypropylene, which transports moisture away up to 40 times more effectively than regular polyester.
Logistics workers in warm warehouses benefit from vests with longer cooling effects. Some models have extra cooling pads to swap out during shifts.
For safety-rated environments, there are vests that meet industry-specific requirements. These combine cooling functions with reflective materials and other protections.
Athletes use cooling vests to optimize performance and recovery. The vests help the body maintain the right temperature during intense sessions.
Training cooling vests are often thin and flexible. Models with front fastenings provide freedom of movement and keep the body evenly cool.
Endurance athletes like runners and cyclists use cooling vests before competitions to lower body temperature. This can extend the time to exhaustion and improve performance when it's hot.
Team athletes sometimes use cooling vests during breaks and warm-ups. Quick-drying materials make them practical for repeated use throughout the same day.
Individuals use cooling vests for everything from gardening to medical needs. They are particularly valuable for people with heat sensitivity.
Everyday cooling vests focus on simplicity and comfort. Many can be machine washed and come with a storage bag.
People with conditions like MS or joint diseases can find relief through temperature regulation. Research shows that a steady, cool body temperature reduces stress and alleviates symptoms.
Leisure users appreciate foldable and lightweight models for camping and festivals. This makes them convenient to take on various adventures.
Choosing the right cooling vest is not always straightforward. Size, technology, and intended use play a role.
The quality of the brand and whether the vest is prescribed also influence the choice.
Cooling vests come in several basic models. Evaporative vests need water and cool through evaporation, while phase change vests use cooling packs that are chilled in a freezer or refrigerator.
Size is determined by both chest and length. Most manufacturers offer sizes from XS to XXL and adjustable fits.
Work cooling vests often have extra durable materials and reinforced seams. For industrial workers, there are models with reflective details.
Medical cooling vests tend to be more discreet for daily use. Dogs? They have their own models adapted for their anatomy, of course.
Cooling time varies between 2–8 hours depending on technology and temperature. Phase change vests last longer but require pre-freezing, while evaporative models work immediately but need replenishing.
The material's breathability and comfort against the skin are important. Vests for work should withstand washing and daily use.
The temperature range indicates at which degrees the vest works well.
Prescribable cooling vests are available for conditions like Dravet syndrome and MS. They require a doctor's prescription and follow-up every three to six months.
Established brands like Vortex and TEMTECH often have better quality control and longer lifespan. Chinese manufacturers may be cheaper, but quality varies.
European suppliers adhere to EU safety requirements and offer local service. North American brands often focus on really tough environments.
Check warranty periods and availability of spare parts before purchase. Specialized suppliers like LincoFun can arrange customized solutions for companies.
User reviews from the same industry or with similar needs often provide the best insight into how the vest performs in everyday life.

Proper use and maintenance are crucial for cooling vests to function optimally. Preparation, cleaning, and storage play a significant role in the cooling effect.
The cooling vest should fit snugly against the body for best function. A thin functional garment or T-shirt underneath is recommended for increased comfort.
For water-based cooling vests:
For phase change cooling vests:
The vest should fit snugly but not too tightly. A covering garment can be worn on top if needed.
Avoid pressing hard against the cooling elements during use to prevent damage.
The cooling elements should be removed before washing. The vest itself can be washed at 60 degrees, regardless of washing instructions.
Afterward, hang the vest up to dry. It must be completely dry before storage to avoid mold.
Store as follows:
Seals and insulation in water-based systems should be checked regularly. Any leaks should be repaired immediately.
The salt mixture in some cooling elements can crystallize over time. Gentle massage can dissolve and restore flexibility.
A functional garment between the skin and the vest increases both comfort and heat transfer. Cotton or synthetic fabrics work best.
To optimize the cooling effect:
For water-based systems, ice during activation can extend the cooling effect. The cooling elements should be evenly distributed over the torso.
The pace of work affects the cooling needs. During intense work, it may be better to have shorter sessions and more changes than to push for too long.
Combine with other cooling products, such as cooling hats, for extra effect. Don't forget to drink more fluids when using a cooling vest – the body needs it.
Cooling vests are primarily used for heat intolerance in individuals with multiple sclerosis and other neurological diseases. They can be prescribed when simpler cooling methods are insufficient.
Cooling vests are actually a central treatment method for individuals with multiple sclerosis who have problems with heat intolerance. When body temperature rises in MS, neurological symptoms can worsen, and functional ability declines rapidly.
Prescription Process:
The goal of cooling treatment is often to improve motor skills and reduce fatigue. Many also find that concentration improves.
Cooling vests can be used together with cooling hats if needed. It's about making everyday life a little easier.
Many users report that they can train and manage daily tasks better with the help of the vest.
Cooling vests are not only used for MS. They can be prescribed for several other medical conditions where heat intolerance is an issue.
Dravet syndrome is an example where cooling treatment can significantly improve quality of life.
Other relevant diagnoses include:
The prescriber may sometimes need to consult the patient's doctor to check for any medical barriers. They also review whether simpler solutions like cold showers, cooling hats, or cooled wristbands are sufficient.
Cooling vests are only prescribed when simpler methods do not provide adequate effect. It's a way to truly tailor treatment to the individual's needs.
The market for cooling vests includes both Swedish and international players, and it feels like the technology is constantly evolving. Smart materials and electronic cooling systems are set to change how both professionals and athletes manage heat.
HyperKewl has become known for its washable cooling vests activated with water. The Plus series is particularly popular among athletes and people working in warm environments.
TST Sweden offers the Flexi series designed with flexibility and comfort in mind, especially for industrial workers. They have a reputation for delivering durable solutions that work in Swedish work environments.
Keep On is somewhat of a one-stop supplier, offering cooling vests, cooling hats, and various accessories. They also promise fast deliveries within Sweden, sometimes within just a few days.
International manufacturers, especially from China, have their niche in making custom cooling vests for companies in Europe and North America. It's often about developing solutions that fit specific brands and needs.
Multi-functional cooling and heating vests are starting to emerge, and it's quite exciting. They can both cool and heat, which feels like the future of temperature control.
Smart wearable devices are now being integrated with cooling vests via advanced electronics. Particularly, Chinese manufacturers are keen on robotics technology and patents for textiles with built-in air conditioning.
New cooling systems keep the user cool for hours after just simple water activation. Perfect for long work shifts in construction and logistics.
Electronic cooling vests powered by batteries are also starting to make their mark. They can provide more precise temperature control and longer usage time without needing to be reactivated constantly.
Cooling vests require some attention to irrigation systems and material choices if you want to get the most out of them. Maintenance, safety, and comfort play a role in both efficiency and lifespan.
Evaporative cooling vests need to be soaked every 2-4 hours, depending on how hot and humid it is. The simplest way to check is to feel the vest from the outside of the fabric.
Gel-based cooling vests are activated by being dipped in water for 10-15 minutes. They retain the cold longer but require a bit more preparation.
Phase change cooling vests are activated by body heat and require no irrigation at all. They work best when it's dry and above 21°C.
Cotton and bamboo fibers are excellent for evaporative cooling as they absorb a lot of water. They retain moisture for a long time and allow air to pass through.
Polymer gel in pockets provides intense cooling for a couple of hours after activation. The material swells when it absorbs water and shrinks when it dries.
Microfiber combined with mesh panels provides good airflow while still retaining moisture. It dries faster than cotton but still cools effectively.
Thin evaporative cooling vests weigh only 200-400 grams when dry and feel barely noticeable on the body. When wet, they weigh more, up to about a kilo.
Gel-based cooling vests are slightly thicker and weigh more even in dry condition, often around 600-1000 grams. They may feel stiff at first but soften once the gel is activated.
Vests with shoulder straps distribute weight better than those that only fasten around the waist. Adjustable straps also improve fit for different body types.
Evaporative cooling vests should be rinsed in cold water after each use to remove salt and dirt. Most models can withstand machine washing at 30°C with mild detergent.
Gel-based vests must not be machine washed, as it destroys the gel capsules. Hand washing with mild soap and air drying is best.
It's important for the vests to dry completely between uses to avoid bacteria. Store them in a ventilated area to prolong their lifespan.
Cooling vests work well up to 45°C if humidity is below 60%. If it’s hotter than that, or more humid, evaporative models quickly lose effectiveness.
One must not forget to monitor hydration and body temperature, even when using a cooling vest. The vest does not protect against dehydration or heat stroke if you do not drink enough.
Gel-based cooling vests are better than evaporative models in really hot and humid environments. They provide consistent cooling regardless of humidity.
Evaporative cooling vests typically last about 12-18 months if used daily and well cared for. The fabric gradually weakens from being soaked and dried repeatedly.
Gel-based cooling vests often last 2-3 years, as the gel itself does not break down as quickly. It’s usually the outer fabric that gives out first, not the cooling system itself.
If you use the vest intensively in really dirty environments, then you can expect the lifespan to decrease significantly—sometimes by half. Many find it worthwhile to rotate between several vests to get the most out of them.
