What a class means on riding clothing
EN 17092 classifies motorcyclists’ protective garments, and it grades them — AAA at the top, then AA, then A, with separate classes for urban and lightweight garments.
The class describes the whole garment: the abrasion resistance of the material, the seam strength, the restraint of the armour, and the coverage. It is not a fabric figure and it is not a marketing tier.
It is printed on a label inside the garment, and that label is what settles what any listing claims.
Why leather still earns its place
A class is a class whatever the material reaches it with. What leather brings is that it abrades predictably and can be repaired, where a torn textile panel is generally finished.
What it costs is weight, drying time after rain, and a break-in period before it fits the way it will fit.
The two things to check on arrival
The class label inside the garment, and what is in the armour pockets. A garment can carry a high class and ship with foam placeholders, and the two are separate purchases wearing one price.
