The Jacket That Excels in a Wide Variety of ConditionsThe Mortirolo is a perennial favorite among cyclists because it’s exceptionally good in a wide variety of conditions. High intensity in cold weather? Yep, this jacket keeps you warm but also vents a lot of moisture out the back thanks to our 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 we 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. Gore Windstopper X-Fast fabric on front is windproof and water resistant Back in Warmer to prevent overheating Front zippered chest vents Silicone gripper at waist keeps jacket from riding up YKK Vision zipper 3 external rear pockets Reflective stripe on back to keep you visible in low-light conditions.

Winters are getting warmer, and this jacket means you’ll be ready. It’s our lightest-weight winter jacket, and we’ve replaced the fleece lining found on most of our winter jackets with a lightly brushed jersey that helps wick moisture away. This jacket provides very little insulation, but with the full Gore Windstopper front and sleeve front you’ll be able to layer it to cover most conditions. Not only is it lighter weight for less-cold conditions, it also has a high degree of stretch and freedom of movement, so it feels great on those transition days between fall and winter. Our lightest jacket for fall or light winter riding Gore Windstopper X-Mid front and sleeves for wind protection with exceptional breathability Warmer fleece fabric on back for additional breathability YKK Vision zipper 3 rear pockets Reflective details on back for visibility.

Ready In Case of EmergencyJust like the name says, we wanted to create the ideal simple jacket. We made it completely waterproof and compact, and, as you’d expect from Castelli, we also gave it an amazing on-bike fit, yet it’s still roomy enough to fit over a Gabba. This jacket is an emergency piece, so we knew you wouldn’t want to break the bank with it, but the only real compromise compared to our top-of-the-line offerings is in breathability. We didn’t make this for an all-day rain ride, but it’s just right for your next emergency. Deluge Light 2.5-layer waterproof fabric keeps rain off with 10,000 mm water column Slight amount of stretch for excellent fit in riding position Folds into half a jersey pocket for emergency situations Innovative “gutters” drain water away from hands and off back Waterproof zipper and seam sealing keep all water out.
