Castelli Mortirolo 4 Windproof Cycling Jacket
The Castelli Mortirolo 4 windproof cycling jacket is ideal for dry winter riding. For some riders, winter riding also includes speed work or even intervals when preparing for a cyclocross race or an early-season Ironman next spring.
No danger of overheating due to the cleverly placed fabrics, protective Windstopper and breathable panels. As spring gets closer you'll appreciate the zippered chest vents - especially when overambitious riding pals are sprinting for town signs or fighting for KOM glory.
Of course, the Mortirolo jacket is also great if you're just cruising around in endurance mode by yourself.
High intensity in cold weather?
Yep, this jacket keeps you warm but also vents a lot of moisture out the back thanks to the Thermal Warmer fabric.
Lower intensity in mild conditions?
Yep, just open up the zippered front vents and use a lighter base layer. The only real trade-off here is that Castelli didn't build in real water repellency other than the Gore Windstopper on the front, but this is a great piece for those dry fall and winter days.
Key Features:
- Windstopper breathable panels
- Zippered chest vents
- Full-length zipper
- Triple rear pockets
- Extended rear coverage
Occasionally, without notice, manufacturers change product design and/or specifications.
