Outerwear

As summer turns to autumn we still have a few months of amazing riding, but when we have to start dressing warmer we miss the freedom of wearing just a jersey. That's why we made this jacket. We used the lightest, stretchiest fabrics we have to make a jacket that cuts out most of the wind, remains highly breathable, provides remarkably high levels of water protection, and just basically disappears so you don't really notice it. This is a performance piece, so we've kept it focused on the task at hand. There's nothing superfluous on it unless you consider the big reflective panel on the back to be unnecessary. We don't. We've given it a close-to-body fit so there's no fabric flapping in the wind, which also helps keep the jacket warmer. The pockets are generous and easily reachable, the zip slides easily, and the logo is discreet. - Polartec NeoShell 4-way-stretch fabric on front and upper sleeves is windproof, waterproof and highly breathable - Nano Flex Light woven fabric on the back is highly breathable while blocking wind and splashes from light rain or wet roads - Close-to-body cut remains very comfortable thanks to 4-way stretch of all fabrics - YKK Vislon zipper is easy sliding for quick ventilation control - 3 rear pockets - Large reflective panel at lower back

If you're looking for just one jacket to do it all, start here. We used our lightest GORE-TEX INFINIUM™ WINDSTOPPER three-layer stretch fabric, which makes it great for milder conditions, and the stretch gives it a great fit. It's the same outer fabric as we use for our Alpha RoS 2 Jacket, called The benchmark in how the best winter jackets should perform" by Cyclingnews.com, but the Go Jacket forgoes the Alpha's integrated liner so you can decide how much insulation you need. Add a Flanders Warm base layer and thermal jersey to extend the comfort range to subfreezing temperatures. But the fabric is only the start. We've tailored the fit to be close to body but not too close. It gives a good drape to the jacket, rounded out by details like the no-sew finishing to the hem and the zippered colored front pocket. The hidden internal cuffs are a nice comfort touch, and you'll appreciate how they eliminate drafts from the wrist. There are three pockets on the back, with a large reflective strip stretching across the entire bottom of the pockets for nighttime visibility. Where does this jacket fit in our line? It's similar in warmth to the Perfetto RoS W Long Sleeve, but it has a more tailored and elegant look, with a slightly more relaxed fit, and it's not quite as protective in wet weather. - Full soft-shell construction with GORE-TEX INFINIUM™ WINDSTOPPER 150 keeps cold wind out while offering exceptional breathability - Excellent stretch with neutral fit for extra comfort - Stretch panel at wrist - Zippered front pocket - YKK Vislon zipper with rubberized zipper pull - No-sew waist construction for a clean, technical look - 3 rear pockets - Large reflective strip across pockets for low-light visibility

The long-sleeve Gabba is one of our most versatile pieces. 100% wind protection with GORE-TEX INFINIUM WINDSTOPPER water protection and best-in-class breathability. With a light base layer it's good for mild temperatures, or with a thermal layer you can ride it below freezing. If you have just one jacket in your cycling wardrobe, this should be it. - Castelli-exclusive GORE-TEX INFINIUM WINDSTOPPER 205 Warm brushed water-resistant fabric on front-facing surfaces - GORE-TEX INFINIUM WINDSTOPPER 203 Stretch on rear-facing surfaces for greater stretch and breathability - Taped shoulder seams for extra rain protection - Top- and bottom-opening YKK Vislon zipper for easy sliding, covered for additional wind and rain protection - Zippered ventilation opening on side of chest - 3 rear pockets - Reflective panel at bottom of pockets

A lightweight packable shell, ideal for stuffing into your pocket in case of rain on those unpredictable days. The Squadra ER jacket will shut out the wind and provide a bit of protection from light rain while still being small enough to pack into your back pocket or seat bag. An essential item for every ride. - Minimalist shell jacket for that long Dolomite descent or unexpected rain shower - Coated 100% polyester ripstop fabric is windproof and moderately water-resistant - Rear vent opening - Camlock zipper - Rear reflective detailing

This is a modern interpretation of the wind shell jacket, the one you keep in your pocket for a long descent or put on for the first hour of the ride until the day warms up. That jacket used to be a simple affair — a nylon shell — but the lack of stretch meant that it had to be cut on the generous side to fit all body shapes, both on and off the bike. We've completely reimagined what the shell jacket should be and how it's constructed. We've added panels on the sides and the sleeves in a very high-stretch yet tightly knit fabric that allows us to give the jacket a modern, close-to-body fit for aero gains on any terrain, and it actually keeps more heat in than a jacket that's flapping about. We've kept it very compact so that it can pack away into minimal space in a jersey pocket. The stretch panels are treated for water repellency, which will help in a light mist, but this is not meant to be a true rain jacket. - Coated ripstop nylon front and back and front of sleeves to keep wind off - Tightly knit stretch panels on sides and sleeves allow for perfect fit - High collar to keep drafts out - Reflective details on chest and lower back for low-light visibility

We've completely re-engineered our entry-level vest. A new coated ripstop fabric keeps the wind off the front and spray off the back, while the tightly knit side panels allow the vest to stretch to fit a wide range of shapes while keeping a close-to-body fit that eliminates fabric flapping in the wind. The collar is cut high and the back long for extra protection and the color blocking of the stretch panels and the reflective details on the chest and tail give it an elegant design touch. - Coated ripstop nylon front and back to keep wind off - Tightly knit stretch panels on sides for perfect fit and ventilation - High collar to keep drafts out - Reflective details on chest and lower back for low-light visibility
