Key Features and Benefits:
- ERT™ Energy Reduction Technology: A patented 4mm layer of lightweight polymer dissipates linear and rotational impact energy. This reduces the likelihood of brain injuries, even during low-speed impacts.
- ConeHead™ Technology: Dual-density foam acts as a crumple zone to disperse impact forces laterally. This added protection minimizes concussion risks and ensures durability.
- 21 Cooling Vents: Strategically positioned vents maximize airflow. This keeps you cool and focused, even during intense rides on technical trails.
- CRV (Crash Release Visor) System: Designed to release on impact, the visor reduces rotational forces on the head. This enhances safety during crashes.
- AGION Anti-Microbial Liner: Specially treated fabric resists odors and bacteria. The liner stays fresher for longer, improving hygiene and comfort.
- 7iDP Rear Dial Adjuster: An easy-to-use adjustment system allows on-the-go fine-tuning. This ensures a secure and personalized fit for any rider.
- FIDLOCK Magnetic Closure: A quick, glove-friendly buckle ensures fast and hassle-free fastening. This improves convenience, especially in cold weather.
- HOLOGRAPHIC Limited Edition Design: A sleek, reflective finish provides a clean and stylish look. This modern design complements any bike or gear choice.
With advanced safety features and unparalleled comfort, the Project.21 is made for riders who demand confidence on every ride. Its lightweight design, impact-reducing technologies, and customizable fit ensure you can tackle technical trails with ease.
