I have a bunch of the Kirkland wool hiking socks from Costco that I really like. For the price, they're absolutely excellent. I think I have one pair of DeFeet Woolie Boolie for winter cycling. I have a couple of merino base layers for hiking/cycling. I have one vintage jersey with World Champion stripes that's wool and the itchy kind. Aside from that, I have tons of nicer clothes that are wool. Some, such as the peacoat and top coat, I've worn cycling in a commuting sense.

I wouldn't mind merino cycling jerseys and the like if I knew more what kind of weather they were for and how they actually feel when riding. I know wool can be good for both hot and cold, but I'm curious as to the real differences. For most things, I want to use a lot of what I have for hiking to also commute. Groups rides and the like are where I'd ride with more cycling specific clothing.
