[Fot] Seat Covers

FOT: 

When I acquired my 1969 TR6 a few years ago the interior had been replaced including the seat covers. Very nice except, the seat covers are not perforated thereby not allowing air to circulate. As a result, my back can get sweaty on longer drivers. Has anyone found a good. ventilated seat cover (mesh, bamboo slats, etc) that lays on top of the seat? My seats have the attached head rests. Thanks.
