Louis Garneau P-09

The draw: Dimpled for speed

The P-09 stands out as the only helmet that utilizes a dimpled texture design, like what is used on a golf ball to increase laminar (read: smooth) airflow. The visor doesn’t enclose the entire opening of the helmet, helping it ventilate and making it feel more open. Two vents—one up front and a large one in the rear—allow for some air to pass through, though you can use a plug for maximum aerodynamics in cooler weather. To keep you from heating up, the internal pads use Icefil technology that turns sweat into a refrigerant.
