This from Davida...
The Davida Jet helmet is handmade in the UK, with a full leather-lined interior and approved to the highest European standard ECER22-05 for the road and ACU Gold Label for the race-track. All Davida helmets are beautifully painted and finished in their factory in Birkenhead looking over the River Mersey to Liverpool.
The Davida Rolling Stones Jet helmet is available at the Saatchi Gallery in London from April to September 2016 SRP £400 and from Davida dealers around the world, excluding North America, or directly from our website www.davida-helmets.com.
