Castelli Women's Alpha ROS 2 Jacket

Now into its third generation, the Women's Alpha ROS 2 Jacket gets a few tweaks here and there, for example, re-engineered double layer cuffs to sit snugly both inside and outside your winter gloves. Enhanced fabrics offer increased breathability but with improved waterproofness too.  Clever design details, such as seam-sealed shoulders and seams, moved out of direct water flow, shut water out yet provide ample breathability and ventilation too. Of course, it also retains all the best features that you love too, including the innovative two-layer construction.

Rain Out. Warmth in. 

The Women's Alpha RoS 2 Jacket, just like its predecessors, makes it far easier to dress for a wide range of conditions. With the RoS (Rain or Shine) design you'll enjoy a best-in-class garment for dry, cold weather but it also offers protection should it rain. In light, but incessant rain, or a sharp rain shower there's no need to immediately have to reach for another waterproof jacket layer.

The Rain or Shine system utilises Gore® INFINIUM™ Windstopper® 150 fabric for wind protection and the high breathability and effective protection required to ride in the rain. Castelli also incorporates its Alpha construction. This separates the wind/water protection layer from the insulating layer. The result is you have better control of ventilation, letting you open the outer layer while protecting your core and better moisture evaporation overall. The  RoS jacket is unlike any other that allows you to ride from low-temperature conditions right through to wet and mild 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.
