HOLOGRAPHIC Limited Edition Series 1

We know riders are looking for something clean and classy that will compliment any bike or kit choice. We’ve done that with the HOLOGRAPHIC Limited Edition Series 1. Keeping things refined and clean, showcasing the shapes and tech, but with a reflective shimmer to break up the black.


Project.21 - HOLOGRAPHIC Ltd Ed Series 1 Trail Helmet

Looking for an open-face helmet with a clean, modern look and advanced protection features? The Project.21 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 P.21 comes with two pad kits to customise 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! And when you get home? Enjoy the Limited Edition padded helmet bag to keep it in the manner such a trick helmet deserves!

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.

The Project.21 comes in our HOLOGRAPHIC Limited Edition Series 1 design for added style points.

The small details that keep you safe and comfortable

ERT "Softer Is Smarter"

ERT (Energy Reduction Technology) is a patented 4mm layer of lightweight soft polymer foam that adds a layer of protection against brain injuries in both linear and rotational impacts.

Unlike most impact energy management materials, which do not deform and dissipate energy below a certain impact threshold, ERT responds instantly, even at low-impact levels commonly seen in riding.

CONEHEAD™ - Shapes, Layers and Materials Working Together to Protect.

CONEHEAD™ helmet technology is one of the world’s most advanced energy management systems available for sport and industrial helmets.

This Patented multi-layer, multi-material, variable density structure uses complex geometry to manage a range of crash impact forces—linear, angular and rotational.

Originally introduced in 2012, CONEHEAD™ is now in its fourth generation of evolution and is lightweight, versatile, easy to work with and affordable.

CONEHEAD™ an advanced structure in its fourth generation

Cone layer geometry and dimensions have been refined for optimal energy management and layer material type and density has been rigorously tested to work as a cohesive and dynamic energy mitigating system

-Outer Layer: EPS foam with inward facing cones

-Middle Decoupling Layer: Softer Contego™ reinforced foam with outward facing cone structure

-Inner Layer: EPS foam with inward facing cones

CONEHEAD™ During Impact

The majority of traumatic head injuries in helmet-related crashes are caused by the combination of linear, rotational and angular impact forces generated by a glancing oblique impact with the ground or hard object. In simple terms: crashing at speed. 

CONEHEAD™ During Impact: Stage 1

On impact, the head pushes against the helmet causing the three layers to compress. Each layer has a specific job to do during impact.

-The inner and middle layers crush and distort. 

-The energy introduced is spread laterally, away from the head. 

-The helmet simultaneously undergoes rapid rotational and angular movement.

CONEHEAD™ During Impact: Stage 2

-The middle Decoupling layer shears, allowing the outer layer to move in relation to the inner layer and head. 

-This decoupling layer works like a slip plane. The helmet effectively ‘moves’ around the head of the rider.

CONEHEAD™ During Impact: End Result

The energies generated from linear, rotational and angular impact forces are dissipated throughout the helmet structure, thereby reducing the impact effects directly transmitted to the brain.

-All three layers have compressed dynamically

-Each material and density has activated in unison 

-Both geometry and materials have worked together to manage impact forces
