Knox Action Pro Trousers

The Knox Action Pro Trouser is a slim-line armoured pant fitted with Class A rated Micro-Lock protection and stretch mesh legs, that can be worn standalone or underneath your exterior layers.

These unisex Action Pro Trousers are low-profile leggings. They offer amazing stretch, abrasion resistance and impact protection while remaining discreet. These have been designed to be worn under motorcycle riding jeans. Since they are CE rated to EN17092- 3 Class A they are tough enough to be worn on their own.   

Designed not just for all types of motorcycle riders, but also for e Bikers and other adrenaline sports participants, such as mountain bikers, skateboarders, snowboarders, or skiers, looking for valuable protection. The Action Pro trousers contain a full set of low profile and discreet Micro-Lock armour, not only in the hips and knees but also on the thigh and coccyx, they’re lightweight, breathable and abrasion-resistant. 

Since they are made using a new sustainable fabric called Sorona® Agile from Dupont, which is an eco-efficient fibre partially made with plant-based polymers they have a subtle piquet texture, high levels of strength, stretch, and stain resistance. All of these features make the hard-working Action Pro trousers perfectly comfortable and hold the armour in the right place.

Action Pro Trousers are part of the Knox Seasonless Collection, simply add a pair of jeans for warmth and Knox waterproof trousers for when it rains. Meanwhile, the stretch mesh on the inside of the trousers adds breathability and comfort in warm weather. The fit is finished with soft and subtle Knox branded elastic on the waist and ankles. The Micro-Lock protectors are removable (for washing the garment) and the protectors come with a five-year guarantee once registered.
