Dirt Pro goggles also include a removable nose guard. This rigid guard shields your nose from roost, rocks, dirt, and debris. Made of a durable rigid material, this guard can withstand even the largest debris that comes at you. Our unique removable design allows you to easily install or remove the mask in a matter of seconds. When installed it says securely fastened and WILL NOT fall off while in use. It also features a unique vented design, which allows a constant flow of air to keep you cool.

509 goggles have the most comfortable foam in the industry, bar none. They feature a triple layer design, which consists of three layers of moisture wicking foam. These layers have a varying density which work together in wicking moisture away from your face and preventing moisture from entering inside the goggle.

509 Dirt Pro goggles come standard with a chrome lens. This single pane, non-vented dirt lens has a durable anti-scratch & anti-fog coating. They are also 100% UV blocking and shatter proof. They also features our innovative three post tear off system. Dirt Pro lenses are easily interchangeable and can be swapped with any of our dirt replacement lenses. Replacement lenses start at $14.95 and are available in four colors including polarized.

A triple silicon lining on the inside of the strap, keep the strap and goggle in place. No more constant adjusting. Set the strap where you want it, and it holds firmly in place all day long, ensuring your goggles are evenly held against your face.

Dirt goggles require a unique vent system in order to keep you cool, yet dust free. We designed the Dirt Pro goggles to provide substantial venting to keep you cool while you work hard under intense conditions. The entire top frame of the goggle is made up of 7 vents, which provide a constant downstream of fresh cool air. The bottom of the goggle features 6 large exhaust ports which release any built up hot air. This 13 vent system works together, to keep a constant stream of fresh air circulating through the goggle. All vent ports are protected by a durable foam cover, which prevent and dust or dirt from entering inside the goggle.

• Foam: Our Sinister goggles feature large oversized face foam. This foam is thicker and extends beyond the frame of the goggle. For a dirt goggle this is not necessary, so our Dirt Pro goggles feature regular triple layer foam that does not extend past the frame edge. By having less foam, you will keep much cooler.
• Nosemask: Our Sinister snow nosemask, is much larger than our Dirt Pro guard. This is because our snow version covers your entire nose and cheeks against freezing cold wind. This is not necessary in a dirt goggle, so our Dirt Pro guard is smaller, covering just your nose. It is also made of a rigid hard material to withstand the impact of rocks and debris.
• Lens: Our Dirt Pro goggles feature a single pane, non-vented dirt lens with tear off posts.
• Tear Offs: The Dirt Pro goggles feature a triple tear off post system that allows you to run tear offs.
• Price: Our Dirt Pro goggles retail for $49.95 compared to $75 for our Sinister snow goggles. Lower price, same high quality.
