What Features Should I Prioritize When Choosing a Cap for Winter Cycling?
When choosing a cap for winter cycling, prioritize features that enhance warmth, comfort, and compatibility with your helmet.
- Insulation: Look for caps made with materials like fleece or wool that provide excellent insulation to keep your head warm in cold weather.
