In that year, Lander Nocchi, a businessman operating in the motorbike and car accessory sector, set up production of motorbike helmets which were injection moulded in polycarbonate, an innovative plastic material developed by General Electric under the trade name of LEXAN™*.This material, which had already been used for the moulding of protective helmets for astronauts on the “Apollo” missions, is still considered the finest thermoplastic material in use for the production of helmets. This was the birth of the first helmet to carry the Nolan brand name (an acronym of the founder’s name). Nolangroup is currently the only company in the sector to produce all of its helmets in Italy through a fully-integrated production process, from the receiving of the raw materials to the final assembly of the product. It is the largest producer of helmets in Europe, with over 400,000 helmets manufactured per year, and a team of 360 people working in a single location which covers an area of 31,000 square metres. Nolangroup produces helmets in polycarbonate, under the brand names Nolan and Grex, as well as helmets in composite fibres, under the X-lite brand. These brands are joined by N-Com, an internal division dedicated to the development of communication systems.
