The AFL maintains there is insufficient evidence to recommend the use of helmets to prevent concussion despite a handful of high-profile players donning new-age headgear from Ireland this season.

This season, Melbourne’s Angus Brayshaw, St Kilda’s Patrick McCartin and most recently Carlton big man Matthew Kreuzer have all worn protective headgear called the “N-Pro,” manufactured by Irish company Contego Sports.

Contego Sports chief executive Mark Ganly said his company’s product, launched two years ago and initially designed for use in rugby, reduced risk factors related to concussion by reducing impact force by up to 75 per cent compared to other helmets, but would not go as far as suggesting it would help prevent concussion.

“We certainly do not make any claims that this is going to prevent concussion. What we’re looking at doing is reducing the risk factors,” Ganly told Fairfax Media from Ireland.
