At 4SR, we never start by asking how a product will look. We start by asking how our gear will perform on your bike. Every cut, every seam, every material has one purpose: maximum safety, function, and comfort while riding.

There's no better testing ground than the racetrack. Every race helps us validate new solutions and push 4SR gear to a higher level of protection and durability for every rider.

We don't make different quality tiers for different price points. Every 4SR suit is built to the same production philosophy and delivers the highest level of quality and protection we know how to offer > 4SR Fair Play

We develop our own technologies to increase safety in real riding conditions. The patented elastic liner and safety seam exist for one reason: to make sure the protective elements do exactly what they're supposed to.

We treat safety standards as a starting point, not a finish line. Thanks to our own technical solutions, race-derived experience, and careful development, we design riding gear to deliver the highest possible level of protection in real-world conditions.

We select protectors from leading global manufacturers for every model. We test each combination carefully to deliver the highest possible level of protection.
