Kask’s bike helmet amnesty in the UK and Ireland, which started last month, runs until the end of August.

If you take an old helmet of any brand to a Kask stockist until 31 August, you can buy a new Kask Vertigo for £100 rather than £165. We should have told you about this last month, to be honest, but what with the Tour de France and everything surrounding it, we didn’t get time. Still, you have over three weeks left to take advantage of the offer.

The Vertigo is Kask’s current flagship helmet although the Italian company have unveiled a new Protone. It was used by Team Sky in last month’s Tour de France and will be available to buy at the start of next year.

We reviewed the Vertigo here on road.cc back in 2010 and concluded that it was a high-quality lid.

“Modern helmets are incredibly robust and should last for five years, but even in the hands of the most careful owners, over time they are at risk of getting bumped, dropped and knocked and this can lead to unnoticed damage to the polystyrene compression layer,” said Angelo Gotti, Kask CEO.

“They’re the most important thing we wear when cycling, so we want people to start thinking about helmets more and to start giving them a routine check – as they would their chain, their tyres or their brakes.”
