Rain protection workwear: Professional protection according to EN 343
When working outdoors in rain, wind, and adverse conditions, professional rainproof workwear is far more than just a useful extra – it is functional protective equipment. The decisive guideline here is the EN 343 standard, which defines the requirements for protective clothing against bad weather.
In our range, you will find models certified according to the current performance classes. Two main values are distinguished: resistance to water penetration (waterproofness) and water vapor resistance (breathability). Whether robust rain jackets or rain trousers – our collections offer protection up to the highest class 4, ensuring your employees remain dry and productive even in heavy rain.

Performance in outdoor use: water column and breathability
Rain protection in tough practical use – such as in road construction, landscaping, or logistics – must withstand extreme stress. A key quality feature here is the water column: professional rain protection workwear should significantly exceed the minimum requirements in order to remain absolutely watertight even when kneeling or carrying heavy loads (pressure on the material).
But "watertight" is only half the battle. Thanks to modern membrane technologies and special coatings, our products have a low RET value (water vapor resistance). This means: moisture from the outside is blocked, while sweat is transported from the inside to the outside. Welded or taped seams also guarantee that no moisture penetrates even at critical points, while full freedom of movement for active work is maintained.
Your benefits: Certified rain protection in our range
- Standards-compliant safety: Certification according to EN 343 for reliable protection against wet weather and wind.
- High water column: Use of waterproof materials that can withstand even mechanical pressure.
- Active breathability: Effective moisture management prevents heat build-up and ensures a comfortable body climate.
- Maximum robustness: Durable fabrics and tear-resistant seams for daily stress on the construction site.
- Flexibility in the system: Available as individual components or as a complete set, often combinable with high-visibility properties (EN ISO 20471).
Through this combination of technical precision and high wearing comfort, our rain protection workwear becomes a reliable partner for all industries that cannot afford a forced break in bad weather.
Requirements for rainproof workwear and material
Professional rainproof workwear must meet clearly defined requirements, with a focus on water resistance, durable materials, and long-lasting construction. High-quality fabrics reliably prevent rain from penetrating while ensuring comfortable wear for daily work.
The requirements for the fabric vary depending on the area of use: while particularly robust materials are necessary for heavy-duty tasks, more flexible options—which stand out primarily for their breathability—are suitable for lighter activities. In technical terms, this clothing is based on the EN 343 standard, which defines protection classes for water resistance and breathability. Only when the material, cut, and workmanship are precisely coordinated can rain protection serve its purpose in the long term.

Comfort and the right choice of waterproof workwear
FAQ: Frequently asked questions about rainproof workwear
When is rainwear needed?
When is rainwear needed?
It is required whenever work takes place in the rain, in strong winds, or in a permanently damp environment.
What components are part of a complete rain protection set?
What components are part of a complete rain protection set?
Typically, the range includes functional rain jackets, sturdy rain trousers, or coordinated complete rain sets.
Is the workwear really 100% waterproof?
Is the workwear really 100% waterproof?
Yes, high-quality models are made from waterproof materials that provide reliable protection against moisture while remaining breathable to prevent heat buildup. In technical terms, this is often classified using performance classes 1 to 4 of the EN 343 standard.
What should you pay particular attention to when buying rainwear?
What should you pay particular attention to when buying rainwear?
Above all, material quality, high water resistance, the right fit, and suitability for the specific area of use are important.
