The fabric is 60% cotton and 40% rayon. Jersey fins in fine gauge. The addition of rayon to the yarn makes it extremely pleasant to the touch. Inside the collar rib is a subtle pinstripe. Armhole, neckline, and shoulder structure are all fully fashioned. To keep the cuff and bottom ribs from stretching out, we used an unique elasticized yarn. It may be worn to work over a button-front shirt or more informally over a t-shirt.
