The Urban Cycling Windbreaker Vest, designed in the USA, is a lightweight breathable cycling gilet that incorporates night visibility reflective trim around the shoulders at the front, on the rear of the neck, and across the back pocket. The rear pocket transforms into a holder pouch for you to fold the jacket neatly into itself, to keep it compact. Underarm ventilation offers high wicking mesh fabric to allow flow of air.
