This is a shirt from Sunny Sports. It's made of cotton herringbone material with a Black Watch pattern. This item shows a lot of attention to detail. I think it can be used year-round. It has been worn, but there are no noticeable stains. A long-sleeved shirt with a green and navy check pattern, with a front pocket for a stylish look. - Brand: SWEET SPORTS - Size: S - Color: Green/Navy Check - Pocket: With front pocket Thank you for looking.
