Proofide top and bottom,and fenders is all you really need for rideing.
When I stop rideing and it's still raining then I put a cover on it,or if I'm leaveing it out overnight when touring.
Had mine for 7 years now,it doesn't look as pretty as it did when new but man is it comfy.
Anyhow does a Brooks saddle really look as good as new after a year or two.
