Send it with the Leatt Chest Protector 3. 5. Featuring level-one chest and back protection, the Chest Protector 3. 5 Pro has us covered for all types of aggressive riding. The 3DF impact foam at the shoulders supplies us with shoulder protection, and the ventilation holes throughout the chest protector ensure we stay cool and comfortable. The removable front and rear plates allow us to customize our protection, and the chest proctor works with Leatt's BraceOn system for use with neck braces.
