The main difference is that we have taken a huge step forward in fabric construction with the Mk2.
The MK2 shirt uses new and exclusive Knox materials that have been engineered for improved abrasion, tear and cut resistance. As a result, we have been able to improve the performance of the Urbane Pro Mk2 and gained a CE classification of AA, which is a standard normally reserved for heavier leather and textile jackets.
Importantly this has been done without a gain in weight, thickness, and no loss of comfort, or breathability. Other subtle differences include new branding. A Knox badge celebrating Knox’s 40-year heritage, new discreet Class AA branding on the inside and a reinforced security belt loop system on the inside which secures the shirt to a pair of trousers.
