What is the fabric weight of your heavyweight t-shirts? Will they shrink after washing?

We primarily offer premium heavyweight combed cotton fabrics ranging from 230gsm to 320gsm, providing a structured fit perfect for street style. All fabrics undergo professional pre-shrinking treatments (washing and tumble-drying) before cutting. This strictly controls the shrinkage rate to under 3%, ensuring garments retain their shape after washing by the end consumer.
