Last winter I was a brand new runner, and just used loose cotton workout pants (sweatpant/yoga pant-types) for my runs. This winter I'm trying to find some better options with more wicking capabilities. I also like stuff that's more form-fitting. So what do you all think of running tights? I like the idea of the compression they offer, and they're sleek and honestly I think they look cool. 8) But they are pretty pricey. Are they worth it?
