The Castelli Race Day T-Shirt has a 60/40 cotton-poly blend which seems to be the magical ratio for the semi-technical tee. It offers the comfort and washability of cotton with the wicking and durability of poly. Most of us have a draw full of T-shirts, but ask yourself how many of them feature fine stitching detail and fitted panels like this garment.
The Race Day is not form fitting, but does have a tapered and tailored-like fit. It looks great with sweats, jeans and pairs with just about everything due to the simple and solid graphics.
