This is a regular-fit, long-sleeve collared polo shirt with a 3-button placket, tonal buttons, and split detail at the sides. It's made from heavy-weight fabric at 200 GSM with 20 singles, using 100% carded cotton (with 15% viscose in marled colors). The shirt features ribbed cuffs, side seams, double-needle bottom hem, and is pre-shrunk to minimize shrinkage, offering both style and comfort.
