When nearly new, I rode my Brooks honey B-17 in the rain for about 50 miles. It got all wet but has fit my butt like a glove ever since then. Also since then I have purchased two more Brook's for my other two bikes.

I sweat more than anyone else in the world and I'm kind of heavy. My butt is like a steam press that makes my saddles fit me to a T. Maybe a hot, sweaty butt makes one a Brooks person.
