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

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

Just like the name says, we wanted to create the ideal simple emergency rain 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

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

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

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

STAY WARM, BE SEEN This is the workhorse jacket in the Castelli winter lineup. We use our warmest GORE-TEX INFINIUM WINDSTOPPER fleece-lined fabric on front and back to keep the wind out and the heat in. There are thermal side panels to let excess moisture escape. We keep the lines clean and don't add anything superfluous – unless you think being seen is superfluous. There are reflective panels on the front and back and both sleeves, which we've designed in a diagonal graphic to make sure you get noticed. Functional details are all there, as you expect from Castelli: easy-slidingYKK Vislon zipper, three big pockets for storage, and a contoured neckline to seal out drafts. - Warm and reflective, the ideal winter cycling jacket - GORE-TEX INFINIUM X-Fast fabric with fleece liner for warmth - Allover protection with Thermoflex side panels for extra stretch and ventilation - Reflective panels on front, back, and sleeves - YKK Vislon zipper for easy-sliding ventilation adjustment while riding - 3 rear pockets - 0°-10°C / 32°-50°F - Weight: 472g
