Castelli Perfetto 4 Winter Jacket

Polartec AirCore™ membrane

The electrospun membrane is semi-breathable: It protects against wind and light rain while allowing warm, moist air from your body to escape. The harder you ride, the harder the membrane works to keep you dry. The fabric weighs 219 grams per square metre and makes the jacket warmer and more protective than previous Perfetto generations.

Chameleon tape on the shoulders

The iconic shoulder taping of the Perfetto range has been replaced by transparent Chameleon tape, which lets the fabric underneath show through while improving water protection in the area most exposed to rain.

Splash tail and pockets with drainage holes

The extended, ergonomically shaped back panel protects your lower back from road spray from your rear wheel. As a nod to the original Gabba, the three rear pockets have metal drainage holes, so that any water that does get in can drain straight out again.

The Perfetto 4 cycling jacket is designed for changeable conditions with the possibility of wind and light rain, and temperatures between 2°C and 12°C.

• Cold and wet spring and autumn rides in changeable weather;
• High-intensity training rides, as the membrane actually works better the harder you ride;
• A thin base layer under the jacket; this combination lets you benefit most from the membrane’s moisture-regulating properties.

• Persistent, heavy rainfall; as the membrane is partially water-repellent, the jacket is not a rain jacket.
• Frost or prolonged extreme cold without an extra layer; in such conditions, you should wear a thicker, insulated jacket such as the Castelli Alpha 150.

• Wear a thin, moisture-regulating base layer under your jacket because the AirCore™ membrane works best when there is moisture to wick away.
• If you’re cycling at a leisurely pace, wear an extra layer. The membrane becomes more active as your exertion increases; at a slow pace, it provides less insulation.
• Wash the jacket on a gentle cycle and do not use fabric softener, which would affect the membrane’s water-repellent properties.
• Allow the jacket to dry thoroughly before wearing it again, especially the pockets with the drainage holes
