Buy black CAT Nexus work trousers: how to choose the right size and fit

Black work trousers need to do more than look smart. For builders, mechanics, installers and tradespeople, what matters most is whether the trousers allow comfortable movement, withstand daily use and provide room for knee protection and tools. That makes the black CAT Nexus work trousers an appealing choice for anyone looking for slim-fit work trousers with practical details.

Even so, many purchases go wrong because of three common pitfalls:

  • A flattering fit is confused with freedom of movement. Narrow-cut trousers can pull at the crotch and knees when kneeling, bending or climbing stairs.
  • “Strong material” does not tell you enough. Check whether the trousers actually feature ripstop fabric and reinforced sections, and where those reinforcements are located.
  • The size is chosen based on the waist alone. With work trousers, both waist size and inside leg length matter. Trousers that are too long can bunch up over work shoes, while trousers that are too short restrict freedom of movement.

What should you look for in CAT Nexus stretch work trousers?

1. Material and reinforcement

According to the product description, the CAT Nexus is made from 50% cotton, 48% polyester and 2% elastane. This combination creates work trousers with stretch, while the ripstop fabric is designed to help limit tearing when the material is put under strain.

Cordura reinforcement is listed in areas prone to wear. These include the knife pocket and knee pockets. Cordura is a brand name for a type of hard-wearing textile; its presence does not mean that every part of the trousers has the same level of abrasion resistance. Pay particular attention to where the reinforcement is positioned.

The trousers also feature a reinforced crotch section and articulated knees. These are practical details for work that involves frequent squatting or kneeling.

2. Knee pockets and protection

If you are looking for work trousers with knee pockets, you should check which type of knee protector fits. According to the product information, the knee pockets on these CAT Nexus trousers are suitable for CW91 knee pads. The reference to EN 14404 relates to certified protection when used with suitable knee pads; do not assume that the trousers themselves are a certified protective device.

Check the following before buying:

  1. Whether the knee pads are included or available separately.
  2. Whether the height of the knee pockets aligns with your knees.
  3. Whether your work requires the use of knee protection.
  4. Whether the knee protection is used in accordance with the manufacturer's instructions.

3. Fit, leg opening and work shoes

The CAT Nexus has a slim fit, straight legs and a 16-inch leg opening, according to the product description. This opening is designed to fit over work boots or other sturdy work shoes. The fit is still a personal choice: if you wear thermal clothing or extra layers, a regular fit may be more comfortable.

According to the product description, the elastane blend helps support freedom of movement. The trousers will not automatically suit every body shape. When trying them on, look for tension around the seat, thighs and crotch. Work trousers should provide room to move without the waistband slipping down.

Choosing the right size: check waist and leg length

The size notation consists of two numbers. The first number refers to the waist size and the second to the inside leg length. The available product variants in this selection include:

  • CAT work trousers size 32/32
  • CAT work trousers size 34/32
  • CAT work trousers size 34/34
  • CAT work trousers size 36/34
  • CAT work trousers size 38/32
  • CAT work trousers size 38/34

Ideally, lay a well-fitting pair of work trousers flat and compare them with the product's size chart. If you measure yourself, measure around the point where you normally wear your trousers. Allow for a belt, underwear and the movements you make during work.

A longer size, such as a 34-inch inside leg, may suit taller users. A shorter size, such as 32 inches, helps prevent excess fabric around the ankle. Always check the latest sizing information on the product page, as fits may vary between models.
