Safe, functional and comfortable work equipment consists of different layers. We also call it the 3-layer system. If you wear three layers, you will stay dry, warm and optimally protected against all risks and circumstances in your work environment. Here we give you tips to ensure that you can perform your work comfortably through your choice of work clothing.
The 3-layer system stands for building up cold-resistant work clothing in three specific layers:
- Thermal clothing and/or thermal underwear
- Insulating intermediate layer
- Protective outer layer
First layer of thermal clothing
It is very important to always start with protective, soft underwear when using the 3-layer system. The base layer consists of thermal clothing. You can then choose a thermal shirt, thermal pants or thermal underwear. Good underwear distinguishes itself by high thermal performance, optimum ventilation and antibacterial protection and extremely fine wearing comfort. Various thermal clothing brands feel like a second skin, such as Helly Hansen thermal and Craft thermo.
Fleece mid-layer
The second layer of the three-layer system is the insulating midlayer. This workwear helps to keep you extra warm at low temperatures and to provide maximum comfort. As an insulating midlayer, sweaters, fleece jackets, fleece vests or fleece sweaters very suitable. Because fleece is so comfortable, it is often used as a vest or sweater. Clothing such as fleece vests, sweaters or jumpers offer easy-care, versatile protection against the cold. The synthetic fibres do not absorb moisture and weigh much less than wool. Fleece is hard-wearing, easy to wash, dries quickly and hardly stretches or shrinks. Perfect as an intermediate layer in the 3-layer system. Brands such as Helly Hansen and Tricorp have a nice selection of fleece jackets, fleece vests, fleece sweaters and sweaters.
Winter work jacket as a third layer
A winter work jacket is the outer layer of the 3-layer system with the standard EN342 or EN14058. This is for protection against cool and cold conditions. It protects you against wind, rain, snow and cold but also ensures that excess moisture is driven away and evaporated. If your work takes place (partly) outside, you naturally want a waterproof work jacket that keeps you warm when the temperatures are low. Many winter work jackets from brands such as Helly Hansen, Black drawers and Hydrowear comply with the EN342 or EN14058 standard.
Workwear accessories
In addition to thermal clothing, fleece clothing and a winter work jacket, you can complete your 3-layer system outfit by choosing various winter accessories, such as a hat, neck protection or a balaclava.
Frequently Asked Questions
When should you wear thermal clothing?
Thermal clothing is worn at low temperatures or when working or exercising outdoors for long periods of time. It is particularly useful if you do not move much or if the weather is changeable. It can also provide comfort indoors in cold spaces. The clothing works best as a base layer, directly on the skin. Make sure you wear it before you cool down, not when you are cold.
How do I know if a winter coat is warm enough?
A warm winter coat can be recognised by its insulation value, the type of lining (such as down or synthetic), and wind and waterproofness. Labels such as "EN 342" or specifications about temperature zones often provide additional information. A good fit without draft holes also contributes to warmth. Test the coat with multiple layers underneath and pay attention to cold bridges at the zip or cuffs. For long-term outdoor use, a coat with breathable, thermally insulating materials is essential.
What are the best winter coats?
The best winter jackets combine insulation, waterproofness and breathability. Brands like Helly Hansen, Mascot, Snickers and Fristads are known for their quality in working environments. Choose a jacket with a windproof outer layer and functional lining (such as PrimaLoft or down) for maximum protection. Extras such as an extended back, adjustable hood and sturdy zippers increase wearing comfort. What is 'best' also depends on your working conditions and preferences.
What are the benefits of fleece?
Fleece is light, soft, breathable and has excellent insulating properties. It wicks moisture away quickly and dries quickly, keeping you warm and dry. Fleece is ideal as a mid-layer in a multi-layer system. The material is often affordable and comfortable for everyday use. In addition, it is easy to maintain and machine washable.
Is fleece made from PET bottles?
Yes, many fleeces are now made from recycled PET bottles. This makes it a more sustainable choice than traditional synthetic fabrics. The PET bottles are melted down and spun into fine fibers that are used to make fleece. This helps reduce waste and contributes to a circular textile chain. Look for labels such as “made from recycled polyester” for clarity.
