Its leather so you need to keep it conditioned and dry. Don't use oil based condition on it, only use wax based conditioners. Profide....you can't go wrong. I use Dr. Martins Wonder Balm. When it starts to rain, I take out my Brooks Cover. It is tough and I can ride with it on the seat. If you use a plastic bag, they tend to wear out quickly or tear. They don't cost all that much but IMO they are worth every penny if they save your seat. Its not just the cost but the time to break them in...ya know.
