RSQ Textured Flannel. The RSQ Textured Flannel for men in black brings a rugged, lived-in twist to a classic look. Crafted from soft, textured flannel fabric, this shirt features an allover plaid pattern enhanced by a washed treatment that creates subtle variations in tone—darker and lighter areas that give it a unique, worn-in character. Designed with a traditional collar and button front, it’s finished with a left chest pocket and long sleeves with button cuffs for timeless appeal. Comfortable, versatile, and effortlessly cool, this flannel is perfect for layering over a tee or buttoning up for a laid-back yet polished vibe.
