I love my wool jersey! I just purchased a 2nd wool jersey a few days ago, should get it in the mail monday or tuesday, its soo oldschool, right out of the 60's style
I also have a pair of wool pants i picked up at a 2nd hand store, i wear these over my lycra tights when riding in the winter, they keep you warm, even when wet. I think i paid $7.50 for these pants, there awesome.
The only downside to wool, is it itches for the first few times, and its a pain to clean, have to do it by hand with woolite (sp?).
