Certainly they were heavy things but what an improvement compared to a Cromwell and Climax goggles! The damn thing can give you a headache without accident!
And I bless the guy who invented the PinLock!
I decided to throw away a race helmet which was still in date, perspiring ruined the inside pads. Last time I wore it was at Silverstone. Difficult decision to take cose he brought many goods things. Driving mainly tin tops I've rather an open face than a full face helmet because of the heat and the better view they offer to the dash instruments for instance and door to door racing too.
