Castelli Women's Tutto Nano ROS JerseyThe Castelli Women's Tutto Nano ROS Jersey gives you the comfort and warmth of a classic thermal cycling jersey. But with the addition of a nanotechnology water-repellent finish, it excels come Rain or Shine. First thing you'll notice when you pull the Women's Tutto Nano (Rain or Shine) Jersey on is the snug stretch fit. This is thanks to the highly flexible Nano Flex 3G fabric, as found in Castelli's superb Sorpasso tights. This close fit not only saves precious energy but less flapping boosts warmth too. Speaking of warmth, the fleece inner is great at trapping body heat and the tight knit of the fabric lets less air through than traditional thermal jersey fabrics, enhancing warmth still further.Next comes Castelli’s proprietary nanotechnology water-repellent finish. When you're cycling in the dry you'll not notice it. However, on a damp and drizzly autumn day, it comes into its own, fending off light rain and wet roads, keeping you comfortable for longer. Spring and autumn days are shorter and so you'll also be pleased to find 360° reflectivity, keeping you visible as the night draws in. An easy-sliding KK® Vislon® zipper with rubberized pull and the silicone gripper elastic finish the jersey in style.If you're looking to upgrade your cool-weather cycling kit, the Tutto Nano ROS Jersey is a great place to start. Compared to a traditional thermal jersey it's a definite step up in performance.Features:Materials: 85% Polyamide, 15% ElastaneNano Flex 3G fabric - warm brushed fleece inside with 20% elastane for stretchNano Flex water-repellent finishReflective fabric inserts at the shoulder and on central pocket3 rear pocketsYKK® Vislon® zipperEmbossed logoSuggested temperature range: 12 to 17 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

The Pro-tier performance of the EQUIPE RS Jersey S9 TARGA is achieved via a number of factors, including continuing with the aerodynamic detailing of its predecessor, careful fabric choice, bonded seam technology and Assos' aggressive RacingFit. Assos RacingFit Made for the WorldTour, you can expect the Assos RacingFit to give you a second-skin fit that seeks to offer maximum performance from your hard-won fitness. With a cut designed to excel in aero riding positions, it will feel strange when you first pull the jersey on. But settle into the drops or bar extensions and it all makes sense. Compression in all the right places also delivers outstanding comfort and support. Fast but Comfortable Fabrics The fast functional fabric mix begins with the use of Assos miniCheck Tex fabric to the front. This 3D knit fabric is extremely elastic to give you the close aero fit needed to go fast, streamlining you to optimise your power output. But not just that, it's highly breathable too, ensuring you don't get overwhelmed with sweat when your race and training efforts intensify. Elsewhere, the rear of the jersey sees Assos' featherweight Stabilizer textile deployed. This holds the jersey smoothly in place thanks to its limited vertical stretch, keeping airflow smooth and uninterrupted while also supporting the rear pockets. Lastly, taking into account a low and aggressive riding position, the raw-cut bonded Push-Pull textile sleeves eliminate any disruptive tape or seams from the leading edge, giving a true lie flat, low drag transition from jersey to skin. Practical Features With the focus on performance, the Assos team haven't overlooked those small practical details that you need when training and racing. To the back, the Triple Ramp Pockets are easily accessible and pre-structured for optimal capacity and stability when loaded. A flap also offers extra security, preventing items from spilling out. An ultralight bonded cam-lock zipper to the front gives you full control of ventilation to the body and a lightweight taped waist keeps bulk low, the fit smooth. And with fabrics offering a range of ultraviolet protection, from UPF (Ultraviolet Protection Factor) 25 to 50, this is a jersey ideal for summer racing.
Assos EQUIPE RS Jersey S9 TARGAWhen it comes to all-out speed on the bike, the Assos EQUIPE RS Jersey S9 TARGA ensures you remain as aero as possible while its outstanding comfort makes it virtually disappear when you’re in the saddle.Proven in the heat and hectic world of summer WorldTour races, the EQUIPE RS Jersey S9 TARGA is the next step in the evolution of Assos' aerodynamic S9 range. Like its predecessor, it retains the same slippery aero details and fabrics, but the TARGA gets some tweaks to make it more comfortable than ever. Assos RacingFitWhen it comes to aerodynamic performance, the Assos RacingFit rewards you with a second-skin feel that won't waste watts. The low-drag, compressive fit feels odd off the bike, but adopt your aggressively low position on the bike and it all clicks into place. Compression in all the right places delivers outstanding comfort and support so you can concentrate on your performance. Fast but Comfortable Fabrics It's not just the fit that is fast. Fabrics are also chosen for their aero gains, as well as delivering outstanding moisture control and comfort. To the front Assos deploys their 3D miniCheck Tex knit fabric.

With just a base layer, this is a wind-protection jersey for mild conditions. Alternatively, use it over a jersey like a vest with added protection on your shoulders. Lightweight, breathable front wind protection with allover water repellency. Lightest Castelli short-sleeve wind protection GORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch lightweight fabric on front and sleeves Nano Flex Light Woven on back for breathable stretch with good water protection Top- and bottom-opening YKK® Vislon® zipper for easy ventilation adjustment on the fly 3 rear pockets Reflective panel at bottom of pockets The Perfetto RoS 2 Wind Jersey started life as a request from our pro riders: I want to wear the Gabba all the time, but sometimes it's too hot. So a somewhat lighter and more breathable Gabba became the Perfetto Light. With the fourth generation, we've also changed the name from Perfetto Light to Perfetto RoS 2 Wind Jersey. And it has become a staple in our autumn and spring wardrobes because it's so useful in so many situations ... which makes it very hard to define. In one sense it's a warmer vest, since it has the same construction as the Perfetto RoS 2 Vest but with short sleeves. In another sense it's a less warm Gabba. In another sense it's a jersey with front wind protection. Regardless of how YOU define it, you'll appreciate how it gives the right amount of protection on cool days while maintaining a high level of breathability. It makes you feel warm and protected, yet offers almost the same lightness and freedom of movement as a summer jersey. For mild days, we'll use it as a jersey over a light base layer with Seamless arm warmers. For rides in cooler or changeable conditions, we'll layer it over a jersey, with either Seamless or Nano Flex arm warmers. The 2 part of the name refers to the updates to the latest version, including a YKK® Vislon® zipper with both top and bottom openings for more adjustable ventilation. The reflectivity on the back is more visible, the three pockets hold more gear, and the extended tail has been reduced to make the piece more packable.
