I used to sell these things and found the RayBan Aviators didn't conform to the head and left a large noisy gap(and i've got a big noggin). David Clarke do sell foam seals to get round this.
Until somebody stole my Serengetis they were my 1st choice, but RayBan have been taken over and thus have a much better up to date range.
ps i'd rather look like a 70's porn star in RayBans than a cyber skateboarding dope dude in Oakley's
