Helmet Nerv 2.0
Nerv by Icaro 2000 is a helmet that has long been a favourite with paraglider, hang glider and microlight pilots all over the world, for its lightness, style and certified safety. But technology is constantly developing, and so we have completely redesigned Nerv with new features to offer even higher levels of performance, protection and comfort. We have recalibrated its internal ventilation, added an inner cap in the high-tech fabric Coolmax, and optimized sizes with two new outer shells. Characteristics that remain unchanged are the Italian design, the appealing style and colours, and the quality of a helmet made exclusively in Italy. We are proud to present Nerv 2.0!

- What our customers say
A new helmet starts from the desired technical characteristics, and it is given form by means of artisanal processes. In fact the first prototype is sculpted from wood and plaster, and it is then scanned and codified into a 3D file. This in turn is used for computer simulations on which colours and detail design can be perfected, and it provides the data necessary for the CNC machines that will cut the dies for the outer shell and the polystyrene inner shell.
Similar processes are used for all the other helmet components, such as ear covers, visor and so forth.
Once everything is ready, the helmet can be assembled, checked for quality, tested and packaged. The finished product is a fine example of Italian design and technological prowess.
Two outer shell sizes, made of strong polycarbonate
The principal reason for this change was to increase safety by means of a higher thickness for the inner polystyrene shell.
The smaller outer shell is 222 mm in width, the larger version is 236 mm in width. A minimal difference, just 14 mm.
But this was essential for passing the stringent impact tests required for EN 966 certification.We have retained the 3mm-thick polycarbonate outer shell, which is both exceptionally light and very strong.
Inner polystyrene shell
Vents on the helmet’s exterior guarantee interior air flow, with two channels between the outer shell and the polystyrene inner shell optimizing comfort and temperature in flight.
The size number therefore corresponds to the head circumference in centimetres, which you can determine using a soft measuring tape.
Please note that as there are two versions of the outer shell, one for the larger and the other for the smaller sizes, it is important to choose the correct version.
If you are in doubt whether to opt for the larger helmet with size 60, or the smaller helmet with size 59, we recommend choosing the larger version. The larger helmet can be adjusted using the rotary size regulator described below even if it initially feels too large. On the other hand, there is no way of adjusting the smaller size 59 helmet if it feels too tight.
Rotary size regulator
It is simple to adjust and the operation can be performed directly by the pilot.
Comfort is ensured by padding on the size regulator’s inner surface.
Interchangeable internal padding
Every Nerv 2.0 helmet has a label that guarantees the use of this famous new textile, which is also soft to touch and so makes the helmet even more comfortable.4 caps are available:for the larger helmet, marked with a label:
- L = size 60 – 61
for the smaller helmet, marked with a label:
- M = size 58 – 59
- S = size 56 – 57
- XS = size 54 – 55
The cap is quick and easy to change for a better fit. Size can be further adjusted using the rotary size regulator at the back of the helmet.
If the helmet is not a perfect fit, we can send you new padding free of charge, independently from where you bought the helmet.
Another important benefit of this internal padding system is that you can easily remove it and replace it with new padding, or simply wash it.
It is made of polycarbonate with anti-scratch and anti-fog treatment.Four versions are available: transparent, tinted grey, orange, mirror.
Foam edging can also be applied to reduce air circulation inside the visor.
Visor fixing system
This modification was also mandatory for EN 966 certification.
There is an O-ring inside the aluminium disc which provides the friction necessary to adjust visor position continuously and smoothly.
When the visor is lifted completely, it is entirely outside the field of vision.
Airflow inside the helmet
Skiing is a sport that requires a lot of energy, and so efficient ventilation inside the helmet is essential. That’s why we introduced ventilation slots that could be adjusted using the thumbswitch at the front of the helmet, a feature that was both stylish and innovative.
But hang gliding and paragliding are sports in which the use of energy is not so high, and that can potentially take pilots to heights at which the air temperature is very low.
So in the new Nerv 2.0 we have eliminated the thumbswitch, while retaining slots that ensure satisfactory ventilation.
For optimum protection, we recommend always using the helmet with the protective ear covers in position.
The Rollbar can be retrofitted to any Nerv helmet: you just have to change the 2 ear protectors.
The Rollbar is also available as a standard feature.Our customers often ask us about the additional protection offered by this component.
The rollbar is fixed to the ear covers, which are in turn fastened securely to the outer shell. This optimizes protection for the chin.
In fact, just as a helmet is designed to absorb impact by energy by the progressive deformation of the polystyrene inner shell and then the outer shell, the rollbar absorbs the energy of an impact to the chin area by the progressive distortion of the entire assembly, rollbar, ear covers and the respective fastenings.
If the rollbar were fixed rigidly to the outer shell, this process of energy absorption would not occur correctly, with detrimental effects on user safety.
Different helmet patterns offer differing degrees of protection.
When compared to the “jet” format, a full-face helmet offers the highest protection, but with slightly reduced visibility when looking downwards.
This is why we have introduced the rollbar concept, which offers an interesting compromise between protection, field of vision and user comfort.
In fact, this helmet with rollbar is a favourite amongst paraglider and paramotor pilots, and for some land sports such as skiing and cycling.
Micrometric chin strap
You just have to press the red button to undo the strap.
The chin strap is padded with soft, comfortable fabric.
But this flexibility also means that it is difficult to maintain an identical colour in successive production runs.
So the finished helmets may show slight chromatic variations.
Of course, once we have defined the desired hue, we do everything possible to ensure that it remains the same, as far as is possible, from batch to batch.
E.N. 966 certification
Our helmets are tested by CSI, an Italian laboratory authorized by Italy’s Ministry of Transport.The Nerv 2.0 is designed specifically for hang glider, paraglider and microlight pilots. It is designed and built to be as light as possible, while optimizing safety.
Like its predecessor, Nerv 2.0 is certified in compliance with the European EN 966 standard.
View the certificate issued by CSI and the complete EN 966 test report.Many pilots ask us if Nerv 2.0 is also suitable for skiing.
Yes, the helmet is ideal for this sport as well, and in fact we are currently obtaining additional certification specifically for skiing (EN 1077).For further information on EN 966 testing, please see our page About safety
Helmet with small outer shell: currently 630 grams, a lighter version is coming soon
Visor 93 grams
It would be cheaper to outsource production overseas. We prefer to do everything ourselves, here in Italy, for a reason: quality, which means safety and user satisfaction. Our quality is not just a slogan: it is demonstrated by tangible results. Our hang gliders and helmets are used by leading pilots who have conquered an impressive list of world championship victories.
And you can see quality in action. You are welcome to visit our workshop and watch our team working on the helmets.
