CASTELLI wanted to make a cycling cap that's great in dry weather yet can protect in case of rain. The trick is a patented system in which the windproof, water-repellent front panel can fold back for complete breathability or fold forward to protect. Better yet, you have three ways to wear it: with the protective panel folded back, moderate breathability with the cap turned around backward, or full close. The Pertex® fabric is ridiculously thin to fit under the helmet, yet has enough air permeability to prevent you from wetting out as you would under a non-breathable cap.
BENEFIT:modern design, suitable under the helmet, combination of materials for maximum comfort
