For motocross, enduro, or mountain bike riders who want serious protection without feeling like a tank, check out the Troy Lee Designs Rockfight CE chest protector. It's built with a slim, breathable profile that fits comfortably under your jersey. The protection is smart: it uses integrated EPP foam in key zones (chest and spine) to manage low-speed impacts, plus a removable, flexible D3O insert in the back for those bigger, harder hits. It's CE certified for safety standards. The side plates are flexible for movement, the shoulder straps are fully adjustable fore and aft, and the shoulder pads are removable if you use a neck brace. The whole thing is ultra-ventilated with channeled bio-foam to increase airflow and keep you cooler. It's featherweight to reduce rider fatigue. Available in Medium/Large size and white color. A top-tier piece of protective gear that doesn't sacrifice comfort or airflow.
