Project 21 Trail Helmet

The 7iDP Project 21 Trail Helmet brings together advanced impact protection, dialed-in comfort, and trail-ready ventilation for riders who demand confidence on every descent. Whether tackling technical singletrack or flowing forest loops, this helmet is built to keep your head cool and protected when the ride gets rowdy.

At its core is the ERT System (Energy Reduction Technology)—a patented 4mm layer of lightweight polymer that helps dissipate both linear and rotational forces in a crash. That means less energy transferred to your head and a better chance of walking away from a tumble. Combine that with 21 cooling vents and a smart airflow design, and you’ve got a helmet that stays cool even when the trail heats up.

The CRV Crash Release Visor System helps the visor detach safely in an impact, while the adjustable dial fit system ensures the perfect snugness for any head shape. Riders will also appreciate the Through Flow goggle ventilation, which keeps eyewear fog-free and stable when the pace picks up. Certified to CE, CPSC, and AS standards, the Project 21 checks every box for safety, performance, and comfort.

Key Features:

• ERT System reduces linear and rotational impact energy for next-level protection.
• Lightweight polymer layer enhances comfort without adding bulk.
• 21 cooling vents maximize airflow on long climbs and hot days.

• Available in multiple sizes: XS/S, M/L, XL/XXL.

For riders who want a lightweight, breathable, and impact-conscious design, the 7iDP Project 21 Trail Helmet blends comfort and protection seamlessly—because confidence on the trail starts from the head down.
