High-visibility clothing is not exactly fashion, but it is designed to make you visible. They use bright colors and reflective materials to make you stand out in hazardous environments.
All of this is governed by EN ISO 20471, and it is indeed critical personal protective equipment – especially where vehicles and machinery are present.
High-visibility clothing is, frankly, a lifesaver in workplaces with poor visibility or where vehicles are moving around. They are made to make you visible from a distance, whether it is light or dark.
The fluorescent material makes you visible in daylight. The reflective bands kick in when it is dark and someone shines a light on you, such as with car headlights.
Critical work environments where high-visibility clothing is a must:
The protective equipment is divided into three levels depending on how much visible material there is. Class 1 is the simplest, while class 3 is for true high-risk jobs.
There are quite a few different types of high-visibility clothing, depending on what you do and how long you will be outside. High-visibility vests are the most common, especially for visitors or when you will only be on-site for a short time.
High-visibility shirts and jackets cover more of the body and are suitable for long work periods. They usually have breathable materials and reflective elements in smart places.
When the weather is really tough, there are winter high-visibility clothes with lining and water protection. They do not lose their visibility just because it is snowing or pouring rain.
| Clothing Type | Usage Area | Protection Level |
|---|---|---|
| High-Visibility Vest | Visitors, short-term use | Class 1-2 |
| High-Visibility Shirt | Daily work | Class 2-3 |
| Winter Jacket | Outdoor, cold | Class 3 |
All high-visibility clothing must be CE marked and comply with EN ISO 20471. Otherwise, they are just regular clothes.
High-visibility clothing consists of three components: fluorescent materials for daylight, reflectors for darkness, and the fabric that holds everything together. The quality of these materials determines how safe the clothing is and how long it lasts.
Fluorescent materials absorb UV light and convert it into visible light. That’s why they are so extremely visible, especially at dawn and dusk.
The most common colors are orange and yellow. Orange is best against a blue sky, while yellow stands out more against greenery. There are actually regulations regarding how bright the color must be according to the standard.
Factors that affect fluorescent materials:
Good high-visibility clothing uses pigments that last longer, but nothing lasts forever. The luminance factor should be at least 70% (yellow) or 50% (orange) when the garment is new.
Reflectors are small glass beads or prisms that return light to the source. In car headlights, you can be seen from several hundred meters away.
Three types of reflector materials:
The reflectors are placed around the arms, legs, and torso so that you are visible when you move. For class 3, there must be at least 0.13 m² of reflective area.
Reflector material performance is degraded by:
The fabric itself determines how comfortable and durable the clothing is. Often, polyester, cotton, or blends are used.
Polyester holds color well and dries quickly, but can feel a bit plastic. Cotton is more comfortable and breathes better, but can shrink and fade.
Clothing for tough jobs needs reinforced seams and ripstop fabric that withstands wear. The fabric weight (grammage) matters – heavier fabric lasts longer but can feel bulky.
Important material properties:
High-visibility clothing endures a lot – both the fluorescent and reflective materials degrade over time. Sunlight, chemicals, and wear accelerate degradation, and eventually, the protection is no longer worth its name.
UV radiation is the number one culprit when it comes to fading fluorescent fabric. The sun breaks down the pigments, and it happens faster than one might think.
Chemicals from detergents, solvents, and other industrial materials can destroy both fabric and reflectors. Strong detergents can fade the color after just a few washes.
Mechanical wear occurs when the clothing rubs against tools, machines, or just rough surfaces. Reflective bands can easily get scratched and lose much of their effectiveness. Bending and stretching create small cracks that degrade both durability and visibility.
Heat – from welding, ovens, or similar – can permanently damage synthetic fibers. Over 60 degrees is actually too hot for most high-visibility clothing.
Dirt and dust are real culprits for visibility. A thin layer of dust can halve the reflectivity – it’s almost shocking.
Moisture and rain can seep into the reflectors and cause them to come loose or become bubbly. This misdirects the light and diminishes the effect.
Temperature fluctuations cause materials to expand and contract at different rates. This can create cracks between the reflective bands and the fabric, which is not ideal.
Chemicals at work affect materials differently. Oils can penetrate and permanently dull the color. Acids and bases can dissolve the binders of the reflectors.
The sun is not as strong year-round, but in summer and in southern Sweden, clothing ages faster. It’s easy to underestimate how quickly this happens.
Color change is probably the most obvious sign that the material is starting to give up. Neon yellow often fades to white or gray-yellow, while orange can shift to a slightly odd pink or red hue as the pigments release.
The reflective bands show visible scratches, cracks, or areas where the reflective layer is missing. When the reflectors no longer shine properly in the light, then safety is not what it should be.
The material's flexibility also goes in the wrong direction when the fibers become brittle. If the fabric cracks when you bend it, or develops permanent creases, it’s probably time to replace the garment.
Do you see seams that have come undone or reflective bands that are hanging loose? Then the entire garment's durability is at risk.
Odor changes—chemical or musty mold—are a clear warning sign. You don’t want that at work.

It’s not always easy to know when it’s time to replace high-visibility clothing, but it is still super important for safety. The equipment gradually loses its effectiveness, whether due to wear, washing, or just tough working conditions.
High-visibility clothing has a limited lifespan, but exactly how long they last depends on how they are used. Manufacturers often specify a maximum number of washes the garment can withstand before the protection deteriorates.
If no exact number is provided, the garment has at least been tested for five washes. That is really on the edge of what can be considered sustainable.
Are you working on roads or construction sites? Then the clothing wears out significantly faster than if you are working indoors or in calmer environments. Dust, dirt, and chemicals really accelerate aging.
Recommended replacement intervals:
Worn high-visibility clothing is dangerous, period. When the fluorescent material fades or the reflectors fall off, you become less visible.
In environments with vehicles or machinery, this quickly becomes a real safety risk.
Main Risks:
High-visibility clothing must be regularly checked to ensure they are still doing their job. Both workers and supervisors should inspect the clothing before use.
Checkpoints:
If the garment does not meet these requirements? Then it should be discarded immediately. Certification and marking according to EN ISO 20471 must be legible. If in doubt, it’s better to discard the garment than to take a chance.
High-visibility clothing is governed by a number of laws and standards that determine both safety requirements and the employer's responsibilities. Neglecting the rules can be costly, both in fines and other complications.
The Swedish Work Environment Authority sets the basic requirements for personal protective equipment in its regulations. Employers must provide the right clothing for employees who risk exposure to traffic.
The Transport Agency has its own rules for road work—everyone must wear high-visibility clothing that meets EN ISO 20471 class 3. This applies to both permanent staff and contractors working on the road.
The colors must be yellow or orange, nothing else. If you work in darkness, fog, or mist, at least class 2 high-visibility trousers are also required.
EN ISO 20471 is the European standard that applies to high-visibility clothing. Garments are classified into three classes based on how much fluorescent and reflective material they have—class 3 is the best.
CE marking is a must on all high-visibility clothing sold within the EU. It shows that they meet safety requirements and have been tested properly.
The standard requires:
Reflectors should encircle the arms, legs, and torso so one can be seen from all directions.
The Work Environment Act states that the employer must ensure that the work environment is safe. This includes ensuring that the right protective clothing is available, without the employee having to pay for it.
The employer must also ensure that the clothing complies with applicable standards and is suitable for the job. This requires that the equipment is reviewed regularly.
Training and instructions are important. Staff should know how the clothing is used, how it should be cared for, and what it cannot withstand.
It is also necessary to document that all of this is actually done and to follow the manufacturer's recommendations for inspection.
The Swedish Work Environment Authority can issue both orders and fines if the employer neglects high-visibility clothing. This can become quite costly, especially if it happens multiple times.
Work Environment Sanction Act allows for large administrative fees, sometimes amounting to hundreds of thousands of kronor depending on the size of the company and how serious the issue is. It does not matter if there are also damages.
If an accident occurs and poor high-visibility clothing was part of the problem, the employer may be liable to pay compensation. The insurance company may also demand money back if the protective equipment was lacking.
The Transport Agency can also stop road work immediately if the staff lack the right clothing. This quickly becomes costly and disrupts production.

High-visibility clothing is divided into three protection classes according to EN ISO 20471, based on how much fluorescent material and reflectors they have. The classification determines how visible you are in different jobs.
Class 1 is the lowest level, with the least amount of visible material. Here, at least 0.14 m² of fluorescent area and 0.10 m² of reflector is required.
Class 2 raises the bar with larger areas, 0.50 m² of fluorescent and 0.13 m² of reflector.
Class 3 is the top tier, with 0.80 m² of fluorescent and 0.20 m² of reflector—maximum visibility.
All must be CE marked.
EN ISO 20471 specifies exactly how much material is required for each class. Fluorescent parts should be visible in daylight, while reflectors should be visible in darkness.
| Protection Class | Fluorescent Area | Reflective Material |
|---|---|---|
| Class 1 | 0.14 m² | 0.10 m² |
| Class 2 | 0.50 m² | 0.13 m² |
| Class 3 | 0.80 m² | 0.20 m² |
The materials must meet requirements for both brightness and retro-reflection. The colors are almost always yellow, orange, or red.
Class 1 is suitable for jobs with low traffic and calm environments, such as warehouses or service jobs.
Class 2 is appropriate when the risks are a bit higher, such as in municipal maintenance, railway work over shorter distances, or at the airport.
Class 3 is mandatory for truly hazardous jobs—road work, highway construction, and emergency services. Here, visibility can actually save lives.
It is the employer's responsibility to ensure that the correct protection class is used, based on a risk assessment of the work environment.
Proper maintenance and washing preserve the reflective properties and safety functions of high-visibility clothing. Improper handling can quickly degrade the materials' protective capabilities and significantly shorten their lifespan.
Regular cleaning of high-visibility clothing is crucial for maintaining both visibility and protective function. Dirt and particles can block the light reflection from the reflective bands.
This reduces visibility in dark environments. Oil stains and chemical contaminants also break down the fluorescent material over time.
It affects color intensity and the material's ability to reflect light.
Cleaning Frequency Depending on Work Environment:
High-visibility clothing is often exposed to several types of contaminants simultaneously.
High-visibility clothing should preferably be washed in 30-40 degree water. Higher temperatures can cause the reflective elements to loosen or lose their effectiveness.
Mild detergent without bleaching or optical brighteners is best. Such chemicals can ruin both color and function.
Important Washing Tips:
Store the clothing in dark, dry spaces without direct sunlight. UV radiation breaks down both the fluorescent material and the reflective components.
Even though high-quality high-visibility clothing can withstand more wash cycles, they still need proper treatment.
Direct sunlight during storage is one of the most common mistakes. UV radiation fades colors and makes the material brittle.
Too high washing temperatures damage the reflective bands. Temperatures above 60 degrees can cause the adhesive to completely release.
Strong solvents and detergents with bleaching attack the material. This leads to permanent color loss and reduced reflectivity.
Mistakes to Avoid:
Inadequate inspection after washing is also a risk. Worn reflective bands or faded areas should be detected in time.
A thorough risk assessment determines which class of high-visibility clothing is required. Certification according to EN ISO 20471 ensures that the protective equipment meets safety requirements.
Expert assistance from suppliers can actually make it easier to find the right clothing for the job.
The employer should conduct a systematic risk analysis. This determines what type of personal protective equipment is needed.
Environments with heavy machinery traffic require higher protection classes than pedestrian traffic. Class 1 is suitable for warehouses and areas with low traffic.
Class 2 is used for road work and construction sites with vehicle traffic. Class 3 is required for highway work, airports, and environments with extremely high risk.
Lighting conditions also affect the choice. Night work and poor weather require better reflectivity than daylight.
The nature of the tasks also plays a role in the garment's design. Moving tasks often require jackets or vests that do not restrict movement.
Approved high-visibility clothing must be certified according to EN ISO 20471. This standard defines the requirements for fluorescent and reflective materials.
The certification process tests the material's durability, color fastness, and reflective ability. Garments without certification cannot be used as personal protective equipment.
CE marking indicates that the manufacturer complies with EU safety directives. The marking should be clear and accompanied by information about the protection class.
Ask the supplier to show valid certificates and test reports. High-quality high-visibility clothing from established manufacturers often has good documentation.
Specialized suppliers like Arbetsskydd Express offer consulting services. They can analyze the workplace's needs and recommend appropriate solutions.
Expert assistance is particularly valuable in complex work environments. Suppliers with industry knowledge can suggest different protective combinations for various tasks.
Feel free to request product samples before larger purchases. Fit and comfort are actually more important than one might think.
Build long-term relationships with suppliers who offer services such as size exchanges and maintenance advice. This way, you will always have access to the right protection as needs change.
Common questions about high-visibility clothing often concern materials, lifespan, and environmental impact during disposal. It’s good to be aware of these things before purchasing new items.
High-visibility clothing is mostly made of polyester and cotton blends. Fluorescent materials have special pigments embedded in polyester fibers for the best color fastness.
Retro-reflective bands contain glass beads or micro-prisms on a polyester film. This provides visibility in headlights, according to EN ISO 20471.
Base garments are sometimes reinforced with ripstop fabric. Some use CORDURA fibers on knees and elbows for longer durability.
High-visibility clothing retains its safety properties for 12-24 months under normal use. If used daily and heavily, it can drop to 6-8 months.
Washing frequency significantly affects degradation. Fluorescent pigments fade after 50-75 washes, depending on temperature and chemicals.
UV radiation breaks down both the fluorescent material and the reflectors. Outdoor work wears out clothing more than indoor jobs.
Wash at a maximum of 40 degrees to preserve the pigments. Avoid chlorine bleaching and tumble drying at high heat—this damages both color and reflectivity.
Air dry in the shade if possible. Direct sunlight during drying fades colors faster than normal use.
Wash high-visibility clothing separately. Velcro and rough materials can damage reflective bands and create holes in the fabric.
Polyester materials in high-visibility clothing decompose very slowly in landfills, sometimes taking 20-200 years. Retro-reflective bands with glass beads do not disappear naturally either.
Burning high-visibility clothing releases carbon dioxide and sometimes toxic substances from the pigments. It’s not great for the environment.
Industrial composting does not work for synthetic high-visibility clothing. Only cotton blends with over 70% natural fiber can decompose biologically, and controlled conditions are required.
Check if the retro-reflective bands still meet the EN ISO 20471 requirements with a simple light test. If the reflectivity is poor, it doesn’t matter how nice the clothing looks otherwise—safety always comes first.
Has the fluorescent color faded too much? Then it’s time to replace it, preferably immediately. Compare it with a completely new product in daylight to see the difference.
It’s smart to plan the replacement before the clothing is completely worn out. Then there is actually a chance that they can be recycled, unlike truly worn garments where options are few.
Several Swedish manufacturers have indeed introduced take-back programs for their high-visibility clothing. These initiatives aim to separate polyester fibers from reflective materials so that the materials can be recycled into new textiles.
At many municipal recycling stations, you can drop off high-visibility clothing in the textile fraction, but metal parts must be removed first. The reflective bands are a bit trickier – they need to be removed manually before submission.
Industrial laundries sometimes collaborate with recycling companies for textile sorting. This collaboration often leads to smoother handling of used work clothes than if individuals were to do the job themselves.
