Compare Leatt, Alpinestars, and Fox chest protectors to find the best match for your riding style. Our expert guide covers protection, comfort, ventilation, and gear compatibility.
A chest protector is a critical part of riding safety, designed to shield your chest, back, ribs, and sometimes shoulders from impacts, debris, and roost. It can help reduce injury severity in a crash and protect against the constant wear and tear of aggressive riding.
The right chest protector strikes a balance between protection, comfort, ventilation, and compatibility with the rest of your gear. Choosing one is not only about how much protection it offers but also how it feels when worn for hours at a time.
