The Knox Action Pro MK2 is an extremely low profile, abrasion-resistant armoured shirt designed to fit underneath your riding gear. Featuring super slimline Level 1 Knox Micro-lock armour at the shoulders, elbows, and a Level 2 Micro-lock back armour insert, this base-layer is suitable for other adrenaline-fuelled pursuits too - from skateboarding and skiing, to eBiking through the city streets.

It’s constructed from an advanced and eco-conscious Dupont Sorona® Agile fabric, partially made with plant-based polymers for abrasion resistance and inherent stretch for long-term comfort, keeping the armour just where it should be - close to the body. Stretch mesh panelling in key areas provides breathability, keeping you cool and fresh on longer rides. The armour is easily removable so you can machine wash the shirt at your leisure, and there is an option to add a chest protector if you’re looking for an upgrade. Zipped pockets allow you to keep your personal items close, and the shirt features thumb loops for added security.

With a sleek, laid-back athletic-inspired aesthetic, and minimal, discrete branding, the Knox Action Pro MK2 is protective enough to be worn solo in the summer heat, or layered up when the weather turns. Offering enough protection for city riders, the Action Pro is a great way to upgrade your urban riding wardrobe.
