The Run 2.0 vest is the optimal running vest for cold temperatures. Improved from our previous model, based on the runner's requirements, this vest feels almost weightless, even with its insulating front padding. The strategically placed padding is made of polyester and provides protection for vulnerable areas in the cold. If the temperature rises, the vest has a chest pocket where you can pack the entire garment, making it easy to take off and adjust. Other features include YKK drawstrings and reflective details for increased visibility. The perfect vest for runs where you need extra protection from the cold.
