She'll make custom ones to fit the wider Brooks saddles too. She made me one for my B68s that's been on my bike since the rainy season started and it's great. It has a flap underneath to keep the underside dry, and stays snugly in place so you can leave it on while riding. Can't recommend it highly enough!

she makes great cycling caps too. Every member of our household, including the 4 and 6 year old, have 'em now.
