Andy, frames were the Oakley Five Squared Ducati edition for ~£36. Lenses are photochromic optilabs with anti-scratch, glare, mist coating for £97 + £5 p&p. This is probably the 3rd pair of lenses I’ve bought from optilabs over the years.
End of last year I got a pair of Oakley glazed Split Jackets and I have to admit the Oakley lenses are definitely superior to the optilabs ones. They just feel better when looking through them.
