The new Beta RoS Women’s Jacket by Castelli follows in the footsteps of all Castelli’s Rain or Shine (RoS) by providing superb dry weather performance and wet weather protection. But it follows in another way too. Like the Gabba and Perfetto before it. It is an absolute revolution in cycling jackets.The Beta is a thin wind and splash barrier that provides a surprising amount of warmth while being incredibly lightweight. At 185g the Beta is lighter than many long sleeve jerseys. In fact, it is so light you will likely not even notice it, but you will still have the protection promised by many jackets.The jacket achieves the triple crown of wind and rain protection, breathability, and low weight by using a combination of Castelli’s lightest and stretchiest fabrics, Polartec® Neoshell® and Nano Flex Light.Polartec® is used on the front and the upper of the sleeves to provide windproof and waterproof protection where you need it most. Nano Flex Light woven fabric is used on the back allowing any excessive moisture and heat to escape whilst also shedding light rain.The Beta RoS women’s Jacket is a performance piece. There is nothing superfluous on the jacket. A YKK® Vislon® zipper provides easy opening and closing even when the pace is high, and 3 rear pockets are just the right size and easily reachable. The only thing that could be deemed superfluous is the large reflective panel, but on cool grey evenings added visibility is always worthwhile.The race fit achieved through the high stretch fabrics and close cut minimises flapping and is reflective of the kind of high intensity, fast riding you will be doing in it.Ride unhindered and focussed on your effort, whatever the weather decides to do. Key Features: Polartec® NeoShell® 4-way-stretch fabric on front and upper sleeves is windproof, waterproof, and highly breathable,Nano Flex Light woven fabric on back is highly breathable while blocking wind and light rain,Close-to-body cut remains 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 on lower back,Race fit,10° – 18°C / 50° – 64°F,Weight: 185g (Small).
The Alpha RoS 2 Jacket from Castelli is the ultimate winter jacket bringing warmth, high breathability, and protection against the rain along with a soft and comfortable fit. The exterior of the jacket is made from GORE-TEX INFINIUM WINDSTOPPER fabric. The lightweight fabric has a unique membrane that delivers the triple crown of being completely windproof, highly breathable, and water repellent, while offering insulation. Minimal seaming and seam sealed shoulders eliminate points where moisture can enter the jacket when you are venturing through mist, wet roads, and even incessant light rain. The unique dual-layer construction of the Alpha is where its insulating qualities really excel. Underneath the exterior layer, the Alpha jacket has an internal vest that hugs close to your body. This offers insulation suitable down to -5C, and it also means you can regulate your temperature with ease. You can open the external layer to allow airflow into the jacket and evacuate moisture without sacrificing insulation and exposing your body to wind chill. A double-layer cuff integrates with winter gloves and a lie-flat waist hugs close to the body to prevent cold from entering at the jackets openings. The stretch fabric is in an updated pattern with a narrower panel between the shoulders and a wider front that makes for a close-to-body fit that minimises flapping and better reflects the shape of your body on the bike. The new cut accommodates a wide range of body types and positions on the bike. Key Features GORE-TEX INFINIUM WINDSTOPPER 150 fabric. Highly breathable wind protection and effective rain protection Minimal seaming with seam sealed shoulders reduces chances for water to enter through stitching Double-layer Alpha construction separates insulating layer from the wind/water external barrier to let you better regulate ventilation Water-resistant YKK Vislon zipper slides easily Raw-edge waist with silicone gripper lies flat and seals out wind Double-layer cuff integrates with glove to prevent cold wind and water entering Stretch fabrics with advance patterning for excellent close to body fit Back ventilation 3 rear pockets with reflective laser-cut drain holes Zippered secure side pocket for valuables -5 10C / 23 50F Weight: 525g (Large)
