RAB says about the Windveil Pull-On Women's
The Windveil Pull-On is built to offer windproof protection on mountain runs or fast hiking days. It combines wind resistant, breathable, and protective Pertex® Quantum Air with strategically placed panels of Motiv™ Aero mesh fabric. As you pick up the pace or face steep inclines, high heat areas enjoy enhanced breathability. Quick drying and fast wicking, it regulates your temperature without breaking your flow while offering protection from howling mountain wind. Tailored for comfort over long distances, the Windveil fits seamlessly over or under a running pack. The deep front zip doubles as a vent with a hold-open popper to keep the air flowing without the jacket flapping. It also enables you to drop the jacket to your waist, without having to stop and pull it over your head. Extended cuffs offer extra protection to the back of the hands and a hem drawcord allows you to adjust the fit and keep the weather out. The Windveil Pull-On has a handy, hidden side pocket for stashing essentials like a card, key or gels, and the jacket itself can be stuffed into the pocket, for storing in a pack until you need it.
