A brown Columbia M-size shirt with excellent breathability. Made with Omni-Shield material, it's suitable for both urban and outdoor use. The fleece lining makes it slightly thick, allowing it to be worn as a shirt-style outer layer. While it might be difficult in mid-winter, it can be worn in spring, autumn, and even winter if it's a bit warmer. The size feels a bit large in both the hem and length, likely equivalent to a size L. - Brand: Columbia - Size: M (Actual size L) - Color: Brown Thank you for viewing.
