Sporty Kevlar jeans that are properly fitted to maximize comfort and keep that sharp sports style and feel! These are the new Club Sport jeans from the 4SR.

When developing the 4SR Club Sport jeans, we have used our experience from World Superbikes technology, to ensure these sporty jeans, work in the same way as our racing Leathers, using flexible panels above the knees.

Flexible and elastic Kevlar® by DuPont, has been used to produce these jeans, to ensure maximized comfort and mobility while riding your motorcycle.

The 4SR Club Sport Jeans also have ventilation that is strategically placed on the upper thighs, right next to the side pockets. The location of the ventilation on the upper thigh reduces the risk of injury from the zip for the wearer. For added safety, the vent is also covered with Kevlar, for extra protection.

Like any other garment we produce at 4SR, the Club Sport Jeans are equipped with quality knee protectors, which are of course to the highest level 2 T + certification and with the ergonomic 3D shape of the protector not only protects the knee but also the shin.

Thanks to the development of our professional riders along with our experience in the world of motorcycle and world championship motorcycle racing, we know that the right shape of the protector is one of the most important aspects.

4SR Jeans are still the only Kevlar jeans on the market that have the fixation of the guards in the right place and meet the highest standard requirements. 4SR have the patented AFS - Armor Fixation System.

How does the 4SR AFS work? The trousers have a loose elastic stocking that holds the knee and shin protector in place and is independent from the top layer of material. So you still have the protector in the right place, while enjoying the freedom and movement of safe Kevlar jeans.
Additionally, you can adjust the protector up and down to position them exactly where you feel most comfortable according to your height.
