Project 21 Pro Trail Helmet

7iDP Project 21 Pro Trail Helmet brings serious protection and ventilation to aggressive trail riders who demand lightweight comfort without compromise. Designed with advanced impact management and a dialed-in fit system, this helmet keeps riders cool, confident, and focused on the ride ahead.

Built around ERT (Energy Reduction Technology), the Project 21 Pro combines a patented 4mm polymer layer with Conehead Technology to dissipate both linear and rotational impacts—helping reduce energy transfer in real-world crashes. A CRV (Crash Release Visor) adds extra safety by detaching on impact, while the 7iDP Rear Dial Adjuster ensures a secure, customizable fit.

Comfort and performance go hand in hand here. With 21 cooling vents and TF (Through Flow) Goggle Ventilation, air flows freely even on hot, technical climbs. The AGION Anti-Microbial Liner helps keep things fresh ride after ride, and the Fidlock Magnetic Closure lets riders snap the helmet on or off with one hand—even with gloves on.
