All right. 180g pure cotton T-shirt is a high-grade fabric with good quality, comfortable wearing, good air permeability, good touch and elasticity, and various colors and styles. T-shirt weight selection: (1) less than 180g: not recommended, thin, transparent and easily deformed. The weight of cotton T-shirts on the market is relatively low, 150g or even lower. Too light weight means thin cloth. If the fabric of the T-shirt is too thin, it means that it is easy to deform and cannot stand cleaning. Maybe you can't wear it after washing it once or twice.

During the period of 180-220 weight, the thickness of pure cotton T-shirt is moderate, which ensures comfort and breathability. The outline can also be kept well, suitable for summer.
