CYCLING JACKET GUIDE
Find the right jacket for every temperature, weather condition, and riding intensity
HOW TO CHOOSE A CYCLING JACKET
A cycling jacket can make the difference between staying comfortable and cutting a ride short when conditions change.
Castelli cycling jackets are designed for different temperatures, weather conditions, and riding intensities. Some prioritize lightweight wind protection and breathability, others add insulation for colder rides, while fully waterproof shells are designed for wet weather
The right choice depends on where, when, and how hard you ride.
CONSIDER THE TEMPERATURE
Temperature is the first reference point, but it should not be considered in isolation. The same temperature can feel very different depending on wind, rain, ride intensity, and what you are wearing underneath.
Use the recommended temperature range as a starting point, then adjust your layers according to your own sensitivity to cold.
RAIN PROTECTION
Not every cycling jacket offers the same level of protection from rain.
Some are designed for wet roads or light showers, while others use fully waterproof constructions for prolonged or heavier rain. If wet weather is likely to define the ride, waterproofness should become one of the main criteria when choosing your jacket.
WIND PROTECTION
Wind can significantly increase heat loss, especially at speed and on exposed sections of the ride.
Some cycling jackets are designed to block most or all of the wind, while others allow a controlled level of airflow to improve breathability during harder efforts. The right balance depends on temperature, intensity, and how exposed the route is.
MATCH THE JACKET TO YOUR RIDING INTENSITY
Harder riding generates more heat and moisture. For high-intensity efforts, breathability can be just as important as insulation.
A more protective or insulated jacket can be appropriate for slower or colder rides, while highly breathable constructions are better suited to riding at sustained intensity.
CHOOSE THE RIGHT FIT
A close Race fit reduces excess fabric and is designed around performance riding. Tailored fits balance a close cycling-specific silhouette with greater versatility, while Regular fits provide a little more room for comfort and layering.
MILD & TRANSITION CONDITIONS
For milder temperatures and changing conditions, a lightweight jacket can add wind protection without the insulation of a full winter jacket.
COOL WEATHER, HIGH INTENSITY
When the pace stays high, managing heat and moisture becomes critical. These jackets prioritize breathability while still providing protection from cool air and changing conditions.

UNDERSTANDING CASTELLI TECHNOLOGIES
The performance of a cycling jacket depends not only on insulation, but also on how its fabrics manage wind, rain, moisture, and airflow.
Castelli uses different technologies across its jacket range to balance protection, breathability, stretch, and comfort according to the intended conditions and riding intensity.
