Certifications and Safety Classifications

Waterproof high visibility clothing must meet certain European standards for both weather protection and visibility. EN 343 applies to waterproofness, while EN ISO 20471 governs visibility class.

EN 343 – Waterproof Properties

The EN 343 standard measures how well the clothing withstands rain and water vapor. There is a rating system from 1 to 3 for both waterproofness (Wp) and breathability (Ret).

Waterproofness is measured in millimeters of water column. Class 1 means 8,000 mm, class 2 is 13,000 mm, and class 3 requires at least 20,000 mm. The higher the number, the better the protection.

Breathability is rated inversely – lower values are better. Class 1 allows >40 m²Pa/W, class 2 is 20-40 m²Pa/W, and class 3 is <20 m²Pa/W. This affects how comfortable the garment is when you work hard.

EN ISO 20471 – High Visibility Classification

EN ISO 20471 divides visibility requirements into three classes. Class 3 is the highest level and requires large areas of fluorescent and retro-reflective material.

Class 3 requires at least 0.80 m² of fluorescent material and 0.20 m² of retro-reflective tape. Both the upper body and legs must be covered to be properly visible.

The background colors are limited to fluorescent yellow, orange, or red. The retro-reflective bands must be at least 50 mm wide and positioned so that the body’s contours are clearly visible.

Additional Certifications for Work Environments

Many work environments actually require more certifications than just the basic standards. Flame resistance according to EN 11612 or EN 11611 is essential for welding and hot metal industries.

Chemical protection according to EN 13034 (type 6) or EN 14605 (type 4) can be combined with high visibility clothing in chemical industries. Anti-static properties according to EN 1149-5 are needed to avoid static electricity in environments where even the smallest spark can cause problems.

SBSC and similar certification bodies ensure that manufacturers truly meet all relevant standards. Regular testing is conducted to ensure that performance holds throughout the clothing's lifespan.

Material Choices and Technical Details

Today’s waterproof high visibility clothing often relies on advanced materials: 2-layer shell fabrics, special linings, and reinforcements in the right places. It’s this technology that ensures the clothing remains waterproof and durable while meeting EN ISO 20471 visibility requirements.

2-Layer Shell Fabric and Its Advantages

2-layer shell fabric is the foundation of quality waterproof high visibility clothing. The outer fabric and membrane are laminated together, creating a barrier that keeps water out while allowing the body to breathe.

With this construction, you avoid separate membrane treatments that can lose effectiveness over time. The lamination ensures that waterproofness actually holds up even after many washes and contact with chemicals in construction and industrial workplaces.

Main Advantages of 2-Layer Construction:

• Permanent waterproofness thanks to the laminated structure
• Better abrasion resistance at seams and connections
• The reflectors work even if the garment gets wet
• Good balance between protection and movement

Insulating Linings and Mesh

3D mesh linings provide a bit of an airy middle layer that helps transport moisture away from the body while insulating against the cold. The mesh construction consists of three-dimensional fibers that create air pockets for warmth without feeling bulky.

37.5® insulation is a smart insulation technology that reacts to body heat and moisture. It works best when the body is around 37.5 degrees, providing consistent comfort.

When combining mesh linings and special insulation, you create a kind of microclimate in the garment. It adapts to how intensely you work and how cold it is around you.

This helps avoid overheating when the pace is high but retains warmth when you’re standing still or taking a break.

Cordura® Reinforcement for Durability

Cordura® reinforcements are placed where wear is greatest – knees, elbows, shoulders. This material is incredibly tough and resists both abrasion and tearing.

The reinforcement is sewn in so that it doesn’t interfere with waterproofness or the function of the reflective materials. Cordura® retains its properties even when the garment is exposed to cold or chemicals.

Placement of Cordura® Reinforcements:

• Knees and Hips: Protects during kneeling work
• Elbows: Extra durability during bending and movement
• Shoulder Areas: Withstands load from tools
• Wrist Locks: Lasts longer when handling materials

Adjustments for Increased Functionality

Modern high visibility clothing is often packed with smart design solutions that make a real difference on the job. Removable parts, ergonomic cuts, and thoughtful pockets make the garments both comfortable and practical.

Removable Hood

A removable hood is one of those details that is often appreciated only when the weather changes or tasks shift. Especially construction workers who move between indoors and outdoors benefit from this.

The hood is usually attached with a zipper or snap buttons along the collar. It’s quick to take off or put on without needing to change the entire jacket.

The material of the hood follows the same reflective standards as the rest of the garment, so you don’t lose certification when it’s on.

Most manufacturers make the hoods adjustable with drawstrings or Velcro. It’s quite nice to know that it stays in place even if it’s windy or you’re moving a lot.

Pre-Curved Sleeves and Extended Back

Pre-curved sleeves are actually underrated. They follow the natural movements of the arm and ensure that the fabric doesn’t stretch or wear as much when you work with your hands above your head.

Extra fabric at the elbows and shoulders ensures that the garment doesn’t constrict when you bend your arms.

An extended back ensures that the lower back is covered even when you bend forward. No one wants a gap at the back, especially not when it’s cold or wet.

This combination of pre-curved sleeves and longer back reduces wear and actually extends the garment's lifespan.

Pockets and Storage Solutions

Pockets are more than just a detail – they must be smartly placed so you can carry tools and items without compromising safety. The placement must not interfere with the reflective surfaces.

Chest pockets are often positioned above the reflective bands and sometimes have pen holders or mobile pockets. Side pockets are reinforced to withstand heavier items.

Different layers of pockets make it easier to keep track of small and large items. Inner pockets are suitable for sensitive items, while outer pockets handle the bulkier ones.

Zippers and Velcro ensure that items stay in place. Some models even have extra secure pockets for valuables or ID cards.

Usage Areas and Work Environments

Waterproof high visibility clothing is most visible in industries where wet conditions and high visibility are a must. These garments combine weather protection with certified reflective technology.

Wet Conditions and Outdoor Work

High visibility clothing that withstands water is crucial for those working outdoors in rain or moisture. Road and railway maintenance requires garments that protect against rain showers while keeping you visible to traffic.

Municipal park and street workers use them every day, often early in the morning when there is both dew and moisture in the air. Port and fishing industries are another group where saltwater and wet surfaces are everyday occurrences.

Rescue services and tow truck operators are out in all kinds of weather and need clothing that works even when conditions are really tough.

Work in Warehousing and Industry

Cold storage facilities and refrigeration units require customized high visibility clothing that can handle condensation and rapid temperature changes. Staff move between different temperature zones, which easily leads to moisture forming on the outside of the clothing.

In the food industry, garments are used during cleaning and sanitizing of production lines. High-pressure washing and strong cleaning agents require completely waterproof protection and visibility.

Warehouses with refrigerated sections need clothing that works in both dry and wet areas. Forklift drivers and warehouse staff must be visible while also protected against condensation and spills.

Construction Sites and Traffic Safety

Concrete pouring and fluid handling on construction sites require class 3 certified waterproof overalls. Workers are exposed to both concrete, rain, and other liquids that regular clothing cannot handle.

Tunnel construction and underground work involve damp environments with poor visibility. High visibility clothing with retro-reflective bands ensures you can be seen even in darker spaces.

Road marking and asphalt laying often occur in busy areas and rain. Here, garments that protect against moisture while keeping you visible from all directions are needed, just as traffic safety regulations require.

Frequently Asked Questions

European standards set the requirements for waterproof work clothing, but it’s the features like breathability and reflectivity that determine how well the garments perform in practice. Maintenance and testing are crucial to ensure that high visibility clothing retains its protection over time.

How are waterproof work clothes classified according to European standards?

The EN 343 standard divides waterproof work clothing into three classes based on waterproofness and breathability. Class 1 provides basic protection in light rain, while class 3 is intended for truly nasty weather.

The testing involves subjecting the material to water pressure for specified times. If the garment withstands 8000 mm water column or more, it is considered waterproof according to the regulations.

To be certified, the entire garment, including seams and closures, must meet the standard. The labeling should show two numbers – the first for waterproofness, the second for breathability.

What features are important for waterproof high visibility clothing in work environments?

Reflective bands and bright colors according to EN ISO 20471 ensure that you are visible, even when it’s dark and wet. The high visibility clothing must remain visible even after becoming thoroughly soaked.

Sealed seams are a must to avoid leaks at shoulders and pockets. Adjustable cuffs and hoods with drawstrings are small details that make a big difference when the wind is howling.

Ventilation openings with waterproof zippers let in air while keeping rain out. Reinforced knees and elbows ensure that the clothing can withstand tough conditions at work.

How do you maintain waterproof high visibility clothing to ensure long durability?

Wash at a maximum of 40 degrees and use mild detergent – skip fabric softeners and bleach, as they ruin the function. Fabric softeners can actually clog the pores in the material and make the garment less breathable.

Air dry rather than throwing the garment in the dryer, as heat can damage the waterproof membranes. It’s best to lay the garment flat to avoid unnecessary strain on the seams.

Regularly impregnate with products designed for the purpose to keep the surface water-repellent longer. If seams or reflectors break, they should be repaired immediately; otherwise, safety is compromised.

What does breathability mean in the context of waterproof high visibility clothing and why is it relevant?

Breathability refers to how much water vapor can escape through the material per square meter per hour. This property prevents moisture from the body from accumulating and turning into condensation inside the garment.

The MVTR value (Moisture Vapor Transmission Rate) shows how effectively the material transports heat and moisture away. Higher MVTR values make the garment more comfortable, especially in jobs where you move a lot.

If breathability is too low, it quickly becomes sticky and warm, which no one wants in the middle of work.

In what ways can waterproofness and durability of work clothing be tested and verified?

Hydrostatic pressure tests show how much water pressure the material can withstand before it leaks. To be considered waterproof, at least 8000 mm water column is required.

Spray tests involve spraying water at the garment at a 45-degree angle for five minutes. Afterwards, it is checked whether water has penetrated to the inside.

Reflectivity tests with photometers are used to see if the high visibility bands truly reflect light as they should according to EN ISO 20471. This is done on both new and worn garments to ensure that the function holds over time.

What are the latest innovations in waterproof high visibility clothing for increased safety and comfort?

Laminated membranes combine several layers of material to find a reasonable balance between waterproofness and breathability. It’s quite fascinating how new polyurethane coatings can provide extra flexibility without compromising protection.

LED-integrated high visibility clothing takes visibility to a new level in poor weather. The battery-powered lighting systems are discreetly built into the reflective bands and do not affect waterproofness at all.

Smart textile technology has also started to emerge, with temperature-regulating properties that adapt to the environment. Microcapsules in the fabric release or absorb heat depending on body temperature – quite clever, right?
