- Castelli Nano Flex shorts. These have some natural water resistance. They're also designed to offer some insulation, but I've been fine riding in them in warm weather. They're also just really comfortable all-around shorts.
- I've got a pocketable rain jacket and shoe covers from
Galibier. They're British, I figure they know a bit about riding in the rain, and their prices are reasonable. I'll wear the jacket if its on the cool side. If you wear it when its warm, you'll get equally wet from your sweat. The shoe covers are more to protect from road spray than rain.
