The classic thermal cut-and-sew from BEAMS BOY has received a modern update. While the flat seam details remain intact, the size has been refined for a better fit. Notably, the straight seam at the armhole has been subtly curved, and the cuffs are now longer with a slightly smaller circumference. This design change allows the sleeves to gather gently at the cuffs, creating an impression of movement around the arms. Additionally, the shoulder width has been adjusted to be slightly wider, enhancing comfort and style.
