Producing only the best, Castelli's Alpha ROS Women's Jacket delivers uncompromised breathability, with insulating warmth effective through wet and dry conditions.

Ideal for the colder seasons, the Gore Windstopper layer enables you to go faster whilst keeping the cold weather at bay.

Castelli Alpha ROS Women's Jacket

Castelli's main goal was to provide a high-quality jacket that works just as well in the dry as it does in the wet. Accomplishing this goal, Castelli presents its Alpha ROS Women's Jacket, delivering optimal water and wind protection without compromising breathability.

The Rain or Shine (RoS) construction of this jacket provides excellent protection from the wind and rain. By utilising sealed seams only where necessary means that the jacket won't allow water to seep in at the most vulnerable points while remaining breathable. The Gore Windstopper technology additionally provides extra protection against the elements, keeping the cool chill out in rapid descents or fast sprints.

The Alpha ROS Women's jacket has two layers, providing effective heat management. By separating the waterproof and windproof layers, increased ventilation, moisture evaporation and most importantly greater insulation results.

Designed around comfort, the raw edge waist and cuffs sit flat against and move with the body, combined with a silicone gripper to prevent the jacket from bunching up. The Alpha ROS presents a close to body fit - this jacket accommodates a wide range of body types.

Perfect for the colder seasons, this supreme and stylish jacket is guaranteed to turn heads through wet and dry.
