The term 'summer suit material' refers to fabrics that are lightweight and breathable, making them ideal for wearing during the warmer months. Two popular materials for summer suits are LINEN and SEERSUCKER. LINEN is a natural fabric made from the fibers of the flax plant, and is known for its strength and absorbency. SEERSUCKER is a lightweight cotton fabric with a crinkled texture, which helps to keep the wearer cool in hot weather.
