Womens Knox Action Pro MK2 Shirt

Womens Knox Action Pro MK2 Shirt

The Action Pro MK2 is the lightest and most breathable armoured shirt Knox has ever made for women. Built with comfort and flexibility in mind, it’s part of a new athleisure-inspired line that blends technical protection with everyday wearability.

More and more riders want gear that doesn’t feel bulky or restrictive — something you can throw on and move freely in, without giving up safety. The MK2 delivers exactly that.

With stretch panels and breathable mesh in all the right places, this shirt keeps airflow high and the fit snug so the armour stays in place — unlike looser jackets where padding can shift around. Knox has been refining this concept since the ‘90s, and it shows.

The 2025 version now features Sorona® Agile fabric from DuPont, an eco-conscious material made partly from plant-based fibres. It’s strong, flexible, stain-resistant, and paired with lightweight four-way mesh and sleek monochrome styling that gives it a clean, technical look.

Two welded outer pockets give you space for essentials, the new mesh cuffs are better for ventilation (and now include thumb loops), and Knox’s belt loop system helps you secure the shirt to your riding trousers. Whether you’re riding on the road or tackling off-road trails, this low-profile shirt is CE-certified to Class A and ready for wherever your ride takes you.
