The Cordura would be nice, but I would like to try some simple slip on covers made of DuPont CoolMax fabric. Don't know how durable it would be used in a seating situation but is sure does help keep a person cool used under motorcycle helmets. If it doesn't cost much, some simple elastic covers could be made up (if You know someone who sews) and once You have a pattern just make several sets. The CoolMax fabric is machine washable. I think if I had to park My tractor outside I would make a cover for the seat out of an old cut down plastic trash can, planter, Rubbermaid/Tupperware tote or something as this would protect from sun, rain, leaves ect. I do park one of My mowers outside and use a womens shower cap to protect exposed PTO shaft splined end.
