The Dainese Thorax Chest Protector is constructed with the front plate in polypropylene, polyethylene foam padding for comfort and the front plate is shaped ergonomically. Dainese understand that no matter how good a back protector is, it is useless if it ruins the ride for you due to being uncomfortable. It has a perforated front plate for temperature regulation along with a liner in double jersey. This is the ladies' version which is better shaped to a woman's figure.
