Seven iDP Project 23 Helmet Fiberglass, Grey & Black

So why “23” in the 7iDP Project 23 helmet? It’s for the 23 large vents designed to flow air across your head for improved comfort.

The Seven iDP Project 23 helmet features the S.E.R.T. (Seven Energy Reduction Technology) which is a slip plane interior with the goal to help reduce the initial shock load during impact.

Seven iDP Helmet Details From 7iDP’s Site:

Whether you’re racing, getting laps at the bike park, or hitting your local trails the Project 23 Fiberglass will keep you protected and comfortable. The Fiberglass shell offers shock absorbency and incredible value for money while the 23 big bore vents for no compromise airflow will keep you cool. Best of all, Project 23 Fiberglass uses our S.E.R.T (Seven Energy Reduction Technology) slip-plane system.

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.

Developed at our Prolab facility on Vancouver Island, our Project Line is the result of endless hours spent designing, developing, and testing in some of the harshest and most demanding MTB riding spots on the planet. We’ve tested all Project lines to destruction and are confident that they’ll provide you with the reassurance that when you do have a big spill – we have you covered.
