7Protection Project.21 Pro MTB Mountain Bike Helmet

Looking for an open-face helmet with a clean, modern look and advanced protection features? The 7iDP Project.21 Pro meets all your requirements.Named after the number of vents, the Project.21 combines massive airflow with the coverage demanded by increasingly technical bike park, all-mountain and enduro trails. This airflow gives a cooling effect to keep you comfortable whilst concentrating on the trail ahead. Like its full-face sibling, the Project.21 uses Energy Reduction Technology (ERT™). This patented 4mm layer of lightweight polymer material dissipates both linear and rotational impact energy. Unlike other systems, ERT™ responds instantly even at low-impact levels commonly seen in riding.In the helmet foam there is additional hidden protection: ConeHead™ technology acts as a crumple zone, dissipating energy laterally. The dual-material, dual-density foam reduces the likelihood (or severity) of concussion. The Project.21 also uses our CRV (Crash Release Visor) system to make sure rotational forces are reduced on impact.That’s a lot of protection technologies in one helmet as we wanted it to be the best open-face helmet in our range and to inspire rider confidence when worn out on the trails.The Project.21 Pro comes with two pad kits to customize your fit, with AGION Anti-Microbial fabric keeping them fresh. The 7iDP Rear Dial Adjuster allows incremental tuning on the fly and FIDLOCK’s magnetic closure makes the buckle a breeze, even with thick winter gloves!The Project.21 is the culmination of so much testing and development: Tech and features providing comfort and confidence on the bike, and the best protection when you come off it, plus it’s been designed to look good when worn.Key Features:ERT™ SystemConehead™ Technology21 Cooling VentsEasy position Visor angleCRV (Crash Release Visor) System7iDP Rear Dial Adjuster with adjustable mounting pointsAGION Anti-Microbial LinerTF (Through Flow) Goggle VentilationFidlock Magnetic ClosureMeets CE, CPSC, AS StandardsSizes: XS/S, M/L, XL/XXLWeight: 402g +/-10g (M/L)Size:X-Small/Small - 52-55cmMedium/Large - 56-59cmX-Large/XX-Large - 60-63cm
