NEAR WEIGHTLESS PROTECTION We have reinterpreted the classic wind vest to make it as svelte as the rest of your wardrobe. This vest is designed to completely block the wind on the front while allowing ample breathability on the back. The fabrics are so impossibly light that you'll be surprised at how much warmer you stay with this vest over your standard jersey. But the magic comes from the cut and the stretch fabric on the back, which take up all the loose fabric and make the vest fit close to body without feeling tight or looking ridiculous. When you're ready to take it off, the vest folds into its rear pocket and stashes away, taking up minimal space in your jersey pocket. - Ultralight windproof woven microfiber front - Striped mesh back is stretchy to avoid fabric flapping in the wind - Folds up extremely small - Rear pocket - YKK Vislon zipper - Reflective piping - 12°-20°C / 54°-68°F - Weight: 75g

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 chest 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 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 a neutral fit for extra comfort - Internal stretch wrist closure for perfect glove interface - Zippered chest pocket - YKK Vislon zipper with rubberized zipper pull - No-sew waist construction for clean, technical look - 3 rear pockets - Large reflective strip across pockets for low-light visibility

NOT YOUR OLD-STYLE WIND JACKET If you're like us, there's a reason you're not using your old-style wind jacket more. With waterproof jackets like the Idro being lighter and more compact than ever, we felt it was time to reinvent a classic. In reality, the Aria Jacket is very different from your flappy old jacket that either didn't protect you or didn't breathe. This jacket is an impossibly light layer that keeps the wind off the front of your body while allowing ample breathability through the mesh side panels. But what you’ll really appreciate is how we use the stretch panels in the sides and on the back of the sleeves to make this jacket fit like a second skin: no flapping fabric, no cold air circulating inside the jacket, no more looking like a throwback to the Armstrong era. This jacket is light and warm enough to wear for the entire ride in mild conditions, but if you do want to take it off it folds into a side panel pocket and stuffs away in minimal space in your pocket or seat bag. - Ultralight windproof woven microfiber front - Striped mesh fabric at sides and sleeve back is stretchy to avoid fabric flapping in the wind - Folds up extremely small - Rear pocket - YKK Vislon zipper - Reflective piping - 10°-18°C/50°-65°F - Weight: 82g

IF YOU HAD JUST ONE JACKET The Perfetto RoS is the one jacket that does everything well. We initially designed it as a cool-weather training and extreme-weather race piece for our pro riders, but in reality, it excels in many conditions thanks to its full wind protection, great fit through stretchy fabrics, and best-in-class breathability. Winter 2019 represents the biggest performance upgrade in the four generations of this jacket. RoS in the name signifies Rain or Shine. The emphasis should be on dry-weather comfort, which is where this jacket really excels, but then you get near waterproof protection if you do get caught in the rain. We worked with Gore to develop two new Castelli exclusive GORE-TEX INFINIUM WINDSTOPPER fabrics. We use a light fleece-lined water-resistant version on the forward-facing surfaces and a lighter, stretchier fabric on the back that maintains the breathability of the previous fabric while improving water repellency at the same time. The Perfetto RoS is that ideal weight: no built-in insulation so you can layer over a light base layer for moderate conditions. Or you can add a thermal jersey underneath and take it to very cold conditions. You decide. The Perfetto family features are all there: excellent fit, easy-sliding YKK zipper, long tail to protect from wheel-spray, reflective panel on the back, and discreet styling that belies the jacket's racing pedigree. This is the one jacket that belongs in every cyclist's quiver. - Castelli exclusive GORE-TEX INFINIUM 205 Warm brushed waterproof fabric on front-facing surfaces - GORE-TEX INFINIUM 203 Stretch on rear-facing surfaces for extra stretch and breathability - Taped shoulder seams for extra rain protection - YKK Vislon zipper for easy sliding, covered for extra wind and rain protection - Zippered ventilation opening on side of chest - 2 rear pockets with pump sleeve are easily accessed with gloved hands - Gabba-style dropped tail with large black reflective panel - 4°-14°C / 39°-57°F - Weight: 305g
