What to Look for in a Waterproof Cycling Cap
-
Waterproofing vs. Water-resistance: GORE-TEX and SealSkinz offer full waterproof protection. Others are water-repellent and suited to light rain.
-
Peak Size: Shorter peaks work better with helmets and in head-down riding. Longer peaks offer more rain protection but may block upward vision.
-
Helmet Fit: Make sure the cap fits comfortably beneath your helmet without pressure points.
-
Breathability: A cap that’s too insulated can lead to sweating — choose breathable materials for high-intensity rides.
-
Seasonality: Some caps add thermal protection; others are designed purely for rain and cooling.
