2019 1LT. Two wks. ago moderate temp ~ 80*f.,1.5 hour drive windows partially down. By time I returned home seat back was damp, T-shirt + cotton shirt sweaty. I don't perspire a lot and am puzzled why leather seats that are full of tiny holes for ventilation would cause this problem. This has happened once before but didn't think much about it. My '75 Stingray has unperforated leather seats without this dampness issue. Any ideas ?
