This is a men's warm innerwear (short-sleeved) that has been stored at home. This product was planned and produced by Fuji Spinning Co., Ltd. in cooperation with Onward Kashiyama and the U.S. company J. Press. Product Features: - Uses hollow fibers that trap a large amount of still air, making it light and very warm. - Highly quick-drying and resistant to losing its shape. - Uses soft cotton on the skin side for a comfortable feel. - Has moderate breathability that doesn't hinder warmth and prevents stuffiness. I am listing this item because it no longer fits. With the cold days continuing, how about some light and warm innerwear? Size: M Chest Measurement: 88-96 cm Material: Cotton 73%, Polyester 27% Color: Dark Gray This item is unused but has been stored at home, so please consider it after understanding this. Thank you.
