Fleece-backed GORE-TEX INFINIUM WINDSTOPPER fabric makes the Castelli Dinamica 2 Womens Jacket warm, windproof and breathable. Ideal for hard rides in cold conditions or lower intensity rides in slightly milder conditions, the jacket is lightweight yet protective, repelling light rain as well as blocking the wind. Reflectivity on the front, back and sleeves improves visibility to other road users from whatever direction they are approaching, and there are three rear pockets for storage.
