Castelli Mortirolo 4 Jacket

The Mortirolo 4 Jacket is a favourite among cyclists because it’s exceptionally good in a wide variety of conditions. This jacket keeps you warm but also vents a lot of moisture out the back thanks to a thermal Warmer fabric. For added ventilation, there are zipped front vents.

The Gore Windstopper® on the front makes this a great piece for dry fall and winter days.


  • Gore® Windstopper® X-Fast fabric on front is windproof and water-resistant
  • Back in Warmer to prevent overheating
  • Front zipped chest vents
  • Silicone gripper at waist keeps jacket from riding up
  • YKK® Vislon zipper
  • 3 external rear pockets
  • Reflective stripe on back to keep you visible in low-light conditions
  • Weight: 393g (large)


Windstopper X-lite: The highly stretchable Winstopper X-lite fabric moves naturally with your body and doesn’t restrict movement. It also delivers 100% wind protection and up to ten times greater breathability compared to other windproof fabrics.
