The perfect jacket for mild winters or for the rider who tends to overheat, this piece features our warmly insulated GORE-TEX INFINIUM™ WINDSTOPPER® fabric on the front and sleeves, while the back forgoes the membrane to let moisture escape. It's a non-race-fit jacket to fit most body shapes. GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric with fleece liner on upper chest and sleeve front GORE-TEX INFINIUM™ WINDSTOPPER® Mid with lightly brushed inside on lower front Reflective panel on chest Warmer back allows heat and moisture to escape Reflective heat transfers on pockets for maximum visibility 3 rear pockets YKK® Vislon® zipper. The Mortirolo Jacket has been designed to be a warm, cozy jacket on cool days while preventing overheating and moisture buildup inside the jacket. Choose this jacket for riding in cool but not frigid temperatures, or for high-intensity rides or if you tend to sweat a lot. This jacket excels in a wide range of conditions as long as it's not bitterly cold or raining. It's the combination of the right fabrics and construction that make it work so well. You get coldest on the upper chest and arms, so we use our GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast three-layer fabric with a luxurious fleece inside for extra warmth. The lower part of the front is in our mid-weight GORE-TEX INFINIUM™ WINDSTOPPER® fabric with a lightly brushed inner face. Both of these fabrics provide 100% wind protection, excellent splash protection, and best-in-class breathability. The back is in our brushed fleece 100% polyester Warmer fabric with superior wicking. It's not windproof, so it lets a lot of moisture escape. You stay drier and therefore warmer and more comfortable. The jacket has a neutral fit. It's not too racy, so there's room for an extra layer underneath, but it's certainly not going to flap in the wind.

Next-level fabric technology makes this jersey faster, water repellent, and warmer even though it's lighter. Like an Aero Race Jersey for cool conditions. Nano Flex Light woven fabric all around partially blocks wind, but lack of a membrane guarantees maximum breathability 3D Mesh fabric from Castelli's base layer range used as front lining for extra warmth and moisture management YKK® Vislon® zipper Raw-cut wrists integrate easily with gloves Close-to-body fit 3 rear pockets Reflective wordmark on back pocket. We've used the Nano Flex Light stretch woven fabric on the back of Perfetto vests and Beta jackets for a few years now. A tightly woven fabric, it keeps a lot of the wind out while being relatively thin and compact. And the lack of a membrane means that much more moisture can escape. Now we bring this fabric into a jersey that is lightweight yet surprisingly warm thanks to the way it keeps more wind out than a traditional jersey. We line the front of the jersey with a fabric that comes straight from our technical base layers for a little added warmth and to help move moisture away from your body. This jersey actually covers a wider range of temperatures than our traditional knit jerseys. Use it with a light sleeveless base layer for mild days, with a light long-sleeve base layer for moderate days, or with a Flanders Warm or Miracolo base layer and vest to stay comfortable in surprisingly cool temperatures. The stretch woven fabric is aerodynamic, and we give this jersey a close-to-body fit. Think of it as your Aero Race Jersey for spring and fall days.

A favorite piece among our sponsored pros, this jersey is a bit lighter and a bit stretchier and features a closer cut for an aero fit. Mid-weight Warmer X-Stretch brushed fabric Ideal for cool conditions, with or without a vest Race cut with highly elastic fabric provides close-to-body fit without feeling tight Drop-pocket construction for better fit around waist and better pocket position Easy-sliding YKK® Vislon® zipper Embossed line across chest Reflective vertical stripe on center pocket. Ideal for cool days when you still want a short-sleeve jersey but need something a little warmer to take the chill off. The fabric is lightly brushed on the inside, and the bit of elastane gives a perfect stretch fit. We'll also use this jersey with arm warmers and a vest on cooler days — either an Aria Vest that will go in a pocket once the air warms up, or a Perfetto Vest for a day that will stay cool. This jersey gives that extra level of comfort underneath. As a piece designed for the pros, it stays wonderfully minimalist: three rear pockets, easy-sliding YKK® zipper, sleeves cut to just above the elbows. But we've added a reflective stripe to help keep you visible.
