7iDP Project.23 Full-Face MTB Helmet

7iDP has delivered a long history of well-designed protective gear. Their Project.23 full-face mountain bike helmet continues that legacy and elevates it to a new level.  Focused on safety, comfort, weight, and good looks, they've created a helmet safe enough for DH laps, but comfortable enough enduro laps at your local trail center.  Check out the details of this new helmet line that includes carbon and glass fibre models, plus a upcoming ABS model.


In debating the characteristics of the Project.23 helmet, we discussed the pros and cons of a hardshell compared to a microshell helmet. We all agreed the prospect of a full-on crash in a microshell helmet wasn’t something we’d want to experience. We just didn’t feel comfortable with the idea of marketing such a design as a gravity helmet

Our design group was unanimous in their opinion that the helmet should have a hard shell construction allied with great ventilation and be as light as possible without compromising its protective characteristics. These beliefs were backed up when we consulted a range of riders from EWS and downhill World Cup racers to local trail riders.


A hard shell ​(think DH/motocross helmet) - has an outer shell made typically of Carbon, Glass Fibre or ABS. The shell protects the EPS foam core from puncture and absorbs energy on impact. A typical micro shell helmet (think XC/trail/road helmet) does not have a substantial outer shell, as a consequence provides inferior protection.


The ‘23’ In Project.23 refers to the 23 full-bore vents that allow air to flow in at the front, move through the specifically designed channels and exhaust heat at the rear. This enables incredible through-flow for ease of breathing while helping you stay cool.


There was no compromise in our choice of materials to ensure the correct balance between protection and weight. This resulted in a weight of 945 grams for the Carbon and 1060 grams for the Glass Fibre model in a size large.


To further augment the safety features of the Project.23 helmet we examined the key questions of how to reduce energy transfer to the brain and reduce rotational force impact.

We studied what was currently on offer; some brands were certainly on the right line, others appeared to be buying into marketing hype. After studying the data it became evident that a reduction in impact energy transfer had to be our primary goal.

Hence the development of SERT - Seven Energy Reduction Technology.


Essentially, SERT is a smart foam with two key functions:

1. Research and dialogue with experts indicated that it is absolutely key to reduce the amount of energy that reaches the brain on impact. SERT does this by absorbing greater levels of energy than an EPS liner alone and can reduce the energy transfer to the brain by up to 20%.

2. Test data indicated that SERT also leads to a reduction in the rotational motion of the brain on impact.


To further reduce the rotational motion of the brain, we designed our visor to break away on impact. The visor snaps on/off, so in the event of a crash it:

1. Releases on impact.

2. Can be snapped back into position or replaced quickly - no bolts to shear and get stuck internally in the helmet.


  • SERT Technology - smart foam liner that absorbs up to 20% more energy and reduce rotational forces
