So the only cycling type clothing that I own is a pair of bib shorts, some gloves, and some Shimano shoes. I usually just rock the rolled up pair of pants and a t-shirt over the bibs and then add layers as necessary. However, most pairs of pants (e.g. Dickies, Levis, whatever) have some form of seam right up the middle that becomes increasingly uncomfortable on longer rides. Also, t-shirts work great, but most of the "outerwear" (or however you classify your hoodies and thrift-store track zip-ups) I own isn't very breathable and stuff. While cycling-specific gear might address these issues, most of it is covered with stupid logos or is just downright ugly.
Any suggestions on bike clothing that is functional without being too techy or loud? Just in case you were wondering: Yes, I have to looked into fabrics synthesized from pies and stash pockets.
