Black work trousers need to do more than look smart. For construction professionals, mechanics, installers and field service workers, freedom of movement, durability and practical storage are essential throughout a long working day. The black CAT Nexus work trousers combine a slim-fit design with stretch, ripstop fabric and knee pockets for knee protection.
However, not every pair of work trousers with knee pockets is automatically suitable for your work. The fit, pocket positioning and compatibility with knee pads are often overlooked too quickly.
Fabric containing polyester or elastane may sound tough and flexible, but the material percentages do not tell you how the trousers are constructed at wear points. So also look for ripstop fabric, reinforced sections and the construction around the crotch and knees.
According to the product description, the CAT Nexus is made from 50% cotton, 48% polyester and 2% elastane. The trousers also feature a ripstop construction and Cordura reinforcements. These are more specific details than a general claim such as “extra strong”.
Work trousers that are too long can bunch up over a work boot or drag on the ground. Trousers that are too short can expose your ankles when kneeling or standing on a ladder. Always check both measurements: the waist size and the inside leg length.
The versions are listed, for example, as 36/32, 36/34, 34/34 and 32/32. The first number refers to the waist size and the second to the leg length. Check the seller’s size chart and compare it with a pair of trousers that fits you comfortably.
Trousers with knee pockets do not automatically include knee pads. For the CAT Nexus, the product description states that the Cordura knee-pad pockets are compatible with CW91 knee pads. The product information also mentions EN14404-certified protection in connection with the compatible knee pads. Before buying, check whether the required knee pads are included or available separately.
Stretch work trousers are practical if you often crouch, climb, kneel or work between obstacles. According to the product description, the elastane and reinforced crotch of the CAT Nexus support freedom of movement. The pre-shaped knees are also designed to provide a more natural posture while working.
Stretch does not mean that every pair of trousers has a generous fit. The CAT Nexus has a slim-fit design with straight legs. If you normally wear a regular fit, pay extra attention to the waist, thigh and seat measurements.
Ripstop work trousers use a woven structure designed to help limit tearing. On this model, Cordura reinforcements can be found around the pockets and knees, among other areas. According to the product description, these sections are designed to provide extra durability.
This makes the trousers an interesting option for work that involves regularly moving against rough surfaces. It is not a reason to consider the trousers suitable for every working environment: always assess the risks at your workplace and check any clothing requirements set by your employer.
For mechanics and installers, a practical pocket layout is at least as important as the fabric. According to the specifications, the CAT Nexus includes:
The straight leg has a 16-inch opening, which the product information says is designed to fit over work boots. However, check the shaft width of your work boots. A wide safety boot may still feel tight beneath the trouser leg.
Why it suits this profile: Size 32/32 is a practical choice for anyone looking for a narrower waist and standard leg length, and wanting to try a functional pair of black work trousers.
The choice is based on verifiable features such as ripstop, stretch, pockets and knee-pad pockets, rather than just a general marketing claim.
50% cotton, 48% polyester and 2% elastane; cargo pocket, phone pocket and hammer loop according to the product description.
Why it suits this profile: This version combines a slim-fit silhouette, stretch and reinforced work zones for everyday professional use.
The reinforced knees, crotch and Cordura pocket sections help tackle wear in areas that are often put under strain during intensive work.
Ripstop construction, Cordura reinforcements and a 16-inch leg opening for wearing with work boots.
Why it suits this profile: The longer inside leg is suitable for users who often wear tall work boots or need extra leg length.
Size 36/34 prevents a suitable waist from being paired with a leg that is too short; however, check the inside leg length in advance.
Reinforced knee-pad pockets, hammer loop and cargo storage; straight leg with a 16-inch opening according to the product information.
Follow the care label and product instructions. The following is stated for the CAT Nexus:
Where possible, wash black work trousers inside out and avoid unnecessarily high temperatures. After washing, check the seams, knee-pad pockets and loops. This allows you to spot signs that repairs are needed in good time and prevents a small defect from becoming a bigger problem while working.
We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Use your waist size and inside leg length in inches as a starting point. A measurement such as 36/32 means a 36-inch waist and a 32-inch leg length. If in doubt, measure a pair of well-fitting work trousers and compare the measurements with the size chart on the product page.
The product description mentions Cordura knee-pad pockets that are compatible with CW91 knee pads. Check the contents of the chosen version before ordering; the trousers and knee pads may be separate items.
According to the product information, the CAT Nexus features ripstop, Cordura reinforcements, stretch and a UPF 50+ rating for outdoor work. According to the manufacturer’s own information, these features are intended for use in outdoor environments. Suitability also depends on your work, the weather and the requirements at your workplace.
