Thin and flexible enough to be folded down into its own pocket, the lightweight jacket can easily be stored in a jersey pocket on every ride. The two-way stretch polyamide fabric has a fluorocarbon-free DWR (durable water repellent) treatment to keep road spray and light showers out. A mesh fabric lining on the collar enhances comfort against the skin. Ventilation holes under the arms improve airflow and heighten comfort. A two-way full-length zipper gives great control of ventilation, as well as easy access to jersey pockets underneath. Reflective POC logos help keep you noticed on the roads in low light.
