  • Castelli Women's Alpha ROS 2 Jacket

    The Castelli Women's Alpha ROS (Rain or Shine) 2 Jacket can take you from a cold, crisp and dry winter day on the bike to a cool, wet and blustery spring training ride. It truly lives up to its 'Rain or Shine' name. 

    This third generation of the Women's Alpha ROS 2 Jacket is the best yet. Updates include improved fabrics to give a boost to performance in the wet as well as enhancing breathability while new double-layer cuffs work better with winter gloves. And it still retains the innovative double-layer construction that makes it so good in so many cycling conditions. 

    Rain Out. Warmth in. 

    Dressing for changeable weather is always tricky. Too warm. Not warm enough. Lots of layers. Rain jacket. It's all a bit much sometimes. However, the Women's Alpha ROS 2 is best in class for your cold, dry days on the bike. And yet come rainy weather, you won't have to immediately reach for a hardshell rain jacket. This is all made possible by the high-performance Gore® INFINIUM™ Windstopper® 150 fabric and double-layer Alpha construction. 

    Gore® INFINIUM™ Windstopper® 150 fabric is completely windproof, superbly breathable and fends off all but the heaviest of downpours. Meanwhile, the Alpha design keeps the outer weather-protective layer from the inner insulating layer. This allows you to keep your core protected while still ventilating the outer layers. The result is more control of body heat, better moisture evaporation and greater comfort across a wide range of conditions. 

    Performance Fit and Features

    Stretch fabrics with advanced patterning make for an excellent close-to-body fit that still accommodates a wide range of body types. A raw-edge waist that lies flat and moves with you plus the Castelli silicone text gripper at your waist keeps the jacket from riding up. 3 rear pockets with reflective laser-cut drain holes plus an extra pocket with waterproof zip make for a very practical jacket with plenty of storage space.

    For those of you seeking the ultimate in versatile all-weather, multi-season cycling protection you really need not look any further. Think of this as taking all your winter kit options and distilling it into one incredible do-it-all garment. We think you'll find it's worth every penny.
