This is a great shirt for the summer, as the fabric is almost sheer, it is so light. The 65% Poly-25% cotton fabric will keep you super cool, no matter how hot or humid it gets. No ironing, machine washable. The two breast pockets have a slight v-shaped stitching on the top, which gives it a slight western look, but also just gives it a casual appearance. Both cuffs have a double button feature. , and there are stays in the collar to keep it in shape. I love the late 60's graphics on the label, and I have no idea what Capital Mercury means. NO flaws that I can see. This is just too small for me, and that is why I am parting with it. These light-weight shirts are hard to find, and as I live in a hot climate (Las Vegas), I buy them when I find them. Go by measurements.
