The first choice of pure cotton, modal you mentioned, and some viscosity of Tencel are all recent new fibers. Compared with cotton, modal has better sweat absorption and breathability, which is similar to cotton, provided that the weaving method is the same. 3. The biggest advantage of modal is that it has a better drape than cotton, which means it won't wrinkle as easily as cotton. 4. The disadvantage of modal compared with cotton is that the strength after water absorption is worse than that of cotton, and there will be some plush and the like. It depends on your requirements. I usually choose cotton. Although modal is a better fabric, it is more unnatural than cotton. Natural things are the best. Especially tight clothes.
