Project.21 Pro Trail 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.

Great filter!
Color: 1Pc-CA10755
Perfect fit in my 2024 Toyota Tacoma TRD Sport! My original one has 25,000 miles on it and honestly, wasn't that bad. But, I knew that if I didn't spend $20 and change it myself, the dealership guys would hound me everytime and try to sell me a $75 filter.

Great value for DIY procedure for my BMW
Color: 1Pc-CA11118
Vehicle information: 2011 BMW 535i GT F07 The fitment is perfect, installation is simple certainly a DIY maintenance procedure. BMW wanted 300$ for install. I compared my oem to this and certainly equal or greater quality so great value. The package includes a manual and a manufacturers sticker with a feedback card. It was sealed with package inside its cardboard. The filter is a beautiful vibrant red. So when it starts to collect debris you will notice I imagine because it’ll shift color but it’s recommended you repose like every 10-15k miles So intend to repurchase this exact filter when needed

Great product

Works great. Better air flow and engine power than the stock Honda air filter. Also cheaper than the OEM air filter.
