This is a Callaway long-sleeved polo shirt. The fabric is smooth, and it doesn't feel bulky when layered with a sweater or other clothing. It has a check pattern, so it's not very noticeable, but there are some areas near the chest logo and on the sleeves where threads are slightly pulled. Size: LL Shoulder width: 45cm, Body width: 57cm, Length: 70cm 100% polyester I'm not sure about the color recently, but I think it's probably navy and white check, although it also looks a bit like a black and light gray check.
