The Duon has a unique chinstrap buckle which can be switched between ‘strong’ and ‘weak’ to offer conformity to either standard, this allows the wearer to be fully compliant in complex environments containing different and changing hazards. 
This particular vented model of the Duon has vents that can be switched to give conformity with either of the required standards.

DUON Updates:
The DUON has been successfully tested following accelerated UV exposure (the equivalent of 25 years in Northern Europe or 10 years anywhere in the world including Saudi Arabia). This was based on 40 hours per week average exposure.
The DUON’s maximum lifespan has been increased to 10 years use. Previously this was limited to 5 years use and 5 years storage (a total of 10 years).

Compatibility:
30mm ‘T-slot’ side fittings for standard ear defenders etc.
Clips for elastic strap mounted lights, cameras etc.
Brackets front and rear for popular cap lamps and other accessories.
Comfort:
Main adjustment to small/medium/large helps keep the helmet centred on the head.
Fine adjustment by ratchet wheel, can be operated with one hand even whilst being worn.
Headband height adjustment allows user to maintain field of view.
6 point head cradle adjustment for stability.
Performance:
EN397 (‘industrial’) has a weak chinstrap to prevent injury if the helmet becomes trapped in machinery etc. and small vents to prevent items such as sparks hitting the wearer.
EN12492 (‘mountaineering’) has a strong chinstrap so the helmet stays in place in a fall – protecting the head, and large vents to help prevent workers getting too hot – an occupational health improvement.
