Funny thing is that is what got me to buying a jersey... It wasn't even a Nike workout shirt... it was the store brand. I realized how nicely they felt in all kinds of weather and while working out... I was running in one and rode my bike in it too. So I thought I would do the jersey thing... just to see what I was missing. Bought one on sale... $40. The feel of of it is pretty cool. Cotton holds in heat and sweat (and yes, I love cotton... ) but the jersey breaths and wicks... (just like everyone always told me).

I started biking back when wool was all the rage and frankly just never could "cotton" to it. The new stuff feels great. Look for a sale.
