Any tips for Moffett & Rain

Just wondering if anyone has any tips for keeping the seat on a rear mounted forklift as dry as possible? With them having an open cab and the great British weather looking for ideas on how to keep it dry from rain and road mess. Its a pain to have to put on waterproof trousers when the drops are on 10 mins apart also eats up precious times doing it repeatedly through out the day.

Put one of these on the seat for driving and remove for using the moffett?
