How to choose the right waterproof work garment? We have the answers you are looking for!


Working in changing temperatures can be difficult. For example, in the fall, the warm summer weather gives way to the cold and rain. Therefore, workers must adapt and wear work clothing capable of withstanding these new temperatures.

To achieve this, you must pay close attention to the waterproof garments used in your workplace. Certain work clothes are made of polyurethane, as others are made of polyester coated with polyurethane or PVC.

Also, the garment’s visibility is essential in the workplace. Therefore, work clothes complying with the high-visibility standard should be a priority against other types of clothing. The CSA-Z96-15 standard about high-visibility safety apparel is an excellent reference.

Finally, it may become essential to find waterproof garments that can be layered over others to keep workers’ warm. A waterproof garment combined with a multilayered system is helpful on cold rainy days.

Waterproof work clothing can have many different features offering variable impermeability levels. Garments made of polyurethane provide optimal protection. This type is watertight, keeping you warm whatever the rain exposure duration.

For polyester garments coated with PVC or polyurethane, water resistance is good, but rain will pass through the fabric after a while. However, if you plan to spend more time in a downpour, this type of clothing will meet our needs!

In addition, it is crucial to ensure the seams are sealed properly. To ensure no water enters through the garment’s seams, a laminated tape must be applied. For improved impermeability, heat-sealed seams ensure optimal imperviousness.

CSA Z96-15 Standard

Waterproof work clothing must first protect you from rain, but what about your safety in the workplace? Most Kosto rain suits comply with the CSA Z96-15 standard on high-visibility apparel.

This standard has been put in place to ensure that workers remain visible to others at all times. If a garment is under one of the three classifications of the CSA Z96 standard, it means it complies with the visibility criteria established by the Canadian standard.

How to choose the proper high-visibility garment?

First, identify the risks found in the workplace and the current environmental conditions. Second, the class of clothing must consider the level of visibility the worker needs in their environment.

Multilayer system

Spring and fall are two seasons where the temperature varies significantly throughout the day. A layered clothing system is an ideal solution for this seasonal problem.

The layered system is based on the idea of many layers of different warmth and protection levels worn on top of the other. When the temperature warms up during the day, you only need to remove a layer and so on. The worker can continue to work without having to change.

During rainy days, rain suits, such as VMK455 shown below, are perfect to be worn over a polar vest as a lining. Then, when the rain stops, the worker can continue to work with only their vest without wearing a big raincoat. On the other hand, remove the polar lining if it continues to rain and the temperature warms up.
