Favorite Shirt

Now if it would only warm up... so I can wear it again.
100% polyester by Sporthill. It's cool and airy compared to regular cotton.
Race t-shirts, in most events, are 100% cotton - ok for winter layering but to hot in the summer.
Lately I've been forfeiting the shirt for a cheaper entry fee.
(A race I ran last year provided caps instead of shirts ~ kewl!)
Anyways, I would like to see more technical t-shirts available in upcoming races.
