A vast majority of my biking clothing has come from TE...even before I worked around the corner from their office/warehouse.

I have a few jerseys from other random places like Terry, Bonktown, or an LBS. When I first started riding and I was collecting bike stuff like mad, I also purchased from Performance and REI pretty frequently. I don't usually do that anymore (unless I see something spectacular) as I prefer to keep my cycling wardrobe limited to only things I REALLY love and not just tons of options.

All of my tri clothing is from either TE or directly from DeSoto when TE didn't have the size/color/style I needed.
