The fabric defines comfort and durability. Cotton is the most popular choice, offering breathability and softness. For performance wear, polyester or blended fabrics provide moisture-wicking properties ideal for active use. In luxury fashion, tshirt for women often feature mercerized cotton or piqué weaves, combining sheen and structure. Linen polos are perfect for summer due to their lightness. High-quality knits retain shape after washing, ensuring longevity.
