Personally I don't care if cycling kits and spandex outfits increase effeciency, reduce drag and provide slightly better aerodynemics., I still refuse to wear them. I don't race against anybody, I don't chase numbers on strava and I am not interested in looking like a pro... so a little bit of loss in performance is irrelevant to me. ..As far as comfort goes, I've been cycling long enough to know what is comfortable and what isn't. If I told the " lycra crowd " that I am comfortable in my non-cycling clothing they wouldn't believe me anyway, so it's pointless to argue with them.
