509's innovative spirit also extended to its goggle line, exemplified by the Sinister X5 and Sinister MX5 goggles. These goggles are beloved for their top-tier optics, durability, and fog-resistance, thanks in part to the unique "Flow" technology developed by the product design team. In a remarkable testing process, the team wore the goggles in front of an industrial-sized fan, subjecting them to a barrage of dirt and debris. The goal was to evaluate the goggles' ability to maintain clarity and prevent fogging, ensuring riders' vision remains unimpeded even in the harshest conditions. 

The introduction of the Altitude Helmets and Sinister X5 goggles showcased 509's commitment to meticulous design and perfect synergy between gear. One of the key highlights of this combination was the seamless fit between the goggles and the helmet's eye port. The design was meticulously engineered to ensure that the goggles slotted perfectly into the helmet, creating a snug and secure connection. This not only enhanced the rider's comfort but also provided an additional layer of safety, preventing any gaps that could potentially expose the rider's eyes to harsh elements. The design of these products was a testament to 509's unwavering dedication to providing riders with gear that not only looked great but also worked flawlessly together, enhancing the overall experience of every adventure. 

The Sinister goggle line didn't stop at the X5 and MX5. 509 continued to innovate with the introduction of the Sinister X7 and Sinister MX6 goggles. These newer additions have pushed the boundaries of goggle technology, setting new standards for performance, durability, and optical clarity. Riders who have adopted these goggles have praised their advanced features, including improved anti-fog properties, comfortable fit, and a design that offers an enhanced field of vision.
