Take the basic cycling cap design and add multiple panels of microfiber polyester and you get the aptly named Performance Cycling Cap. It is better in every possible way when compared to the standard cycling cap. The multiple panels feature a superb fit, while the perforated poly panels wick moisture, dries quickly and provides ample ventilation. 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, one size fits all. Choose your color.
