Sorry, I must have imagined them, then. My apologies for wasting everyone's time.
Seriously, if you have an iron ass, good for you. I'm totally serious and I envy that. Others do not. The basic message is this: if you need special cycling clothes you'll know it. Your nethers hurt or you're getting saddle sores, get some shorts. Your shirts are always getting sweat soaked and clammy and it's bothering you, maybe it's time to get some wool or synthetic jerseys. And so on.
Don't buy because that's what people tell you you need, buy because you realize you need it. Me, I have a helmet, mesh-back half-finger gloves, and padded shorts. For the rest it's jeans or shorts, cotton T's, and sneakers with toe clips. On cold days I throw on some synthetic long undies and a synthetic long sleeve jersey I got at Target and some fake wool lined leather work gloves.
