Doodads, thingamajigs, and whatsits just slow you down, so Arc'teryx made the Cita Women's Vest with a super-simple streamlined design, with the features you need to go fast but nothing to weigh you down. Made of wind-resistant Lumin nylon ripstop and finished with a water-repellent DWR treatment, the Cita also has a mesh back for breathability, a hip pocket for your phone or energy gels, and reflective blazes to keep you visible on those early-a.m. runs.
