Many of the people on the iBob list sing the praises of wool bicycling clothes. I kind of thought it was all a bunch of eccentric iBob wierdness, but I’ve been wearing a Ktena merino wool top for a few weeks now, and I really like it.
The main advantage is that wool feels more comfortable over a larger temperature range than the synthetics. The downside is that it’s way more expensive, and you have to be careful about how you wash it.
On the way home today, a big hawk was sittting in a field along the road. As I rode up, he took off and flew maybe 2 feet over my head. I was able to get a real close look at his belly feathers. It was awesome. Those poor bastards in cars don’t know what they’re missing.
