I have a full rain gear kit from J&G, gortex booties and a gortex cycling hat. My ride is only 6 miles one way (hilly), but I find it pretty nice. The only thing I can say is if it is hot and raining, you are going to sweat. Keep that in mind. Bicycles are all made for rain as far as I know. Never had an issue with any of my bikes. Keep them waxed and clean.

This hat is GREAT and keeps rain off glasses.
