Simply put, monolayer jeans are made by weaving abrasion resistant fibres with other functional fibres into one actual layer, instead of the layers being placed on top of each other. This creates a monolayer fabric.

• LIGHTWEIGHT AND BREATHABILITY - The main appeal is comfort. People ride motorcycles because they're fun. It should never feel like a chore, so the last thing you want is to be weighed down by heavy or uncomfortable gear. Monolayer jeans are lighter, so they'll feel more natural and flexible. In the summer, this will be totally handy, because lighter jeans won't feel nearly as hot when you're riding in those scorching afternoons.
• HIGH SAFETY - Monolayer jeans will usually offer premium protection than lined denim. This is because when the abrasion resistance material is weaved into the fabric, there will be a larger area of protective coverage, respectively it allows the whole surface to be abrasion resistant.
• UNIQUE STYLE - Monolayer jeans also are more stylish. The lighter weight allows for jeans to be made in a skinny fit and the overall lack of bulk means that your riding pants will look a lot closer to a casual pair of jeans.
