Take the basic cycling cap design and add multiple panels of microfiber polyester and you get the POC Essential Road Cap. It is better in every possible way when compared to the standard cycling cap. The multiple panels feature a superb fit, with a microfiber polyester front that wicks moisture and provides some inflow, while a poly-back allows maximum release and outflow. The classic design cues look perfectly appropriate. Overall, the volume of the cap is low, so it will fit under your helmet without issue. As with most cycling caps, the material stretches, so one size fits all.
