Alpha Flight RoS Jacket

The Alpha Flight RoS Women's Jacket is Castelli's best for riding in mild winter conditions, made with wind protection on the front and sleeves, breathability and light water repellent on the back and a separate insulation layer to aid temperature regulation.The areas of the jacket most likely to encounter the elements are made from wind repellent but highly breathable Nano Flex Light, while the back is Nano Flex Extra Dry. This is even more breathable, allowing maximum dispersal of heat and moisture, so that you never have to worry about overheating or getting chilled by sweat when you stop.The inner layer, meanwhile, is warm but very light Polartec® Alpha. It's found at the sleeves, at the back, and most importantly as a separate vest layer at the front. This construction gives the jacket its versatility, ensuring that the layers can be closed one at a time or together, depending on whether fighting the elements, warmth or full-on protective cosiness are your priority at different parts of the route or as the weather fluctuates.Castelli's best jacket for mid-winter challenges and riding on a cool dayOuter front, upper back and sleeves made from wind resistant, airy Nano Flex LightLower back made from highly breathable, wind resistant Nano Flex Extra DryMaterial has been treated with nanotechnology, water repellent finishWith warm yet light Polartec® Alpha layer at back, on sleeves and forming vest frontSeparate wind block and insulation layers aid regulation of temperature and ventilationPartially covered double zipper and small zippered pocket further aid ventilationRaw edge waist lies flat, moves with youThree rear pockets with laser-cut, reflective drain holesMade for a temperature range of 6-16°CWeighs 249g (S)
