Adi's CLIMA LITE is mostly in spring and autumn, although it will sweat but not cool enough, mainly polyester and cotton. In summer, CLIMA COOL is mainly polyester, and Nike's DRI-FIT is also mainly polyester, which also pays attention to perspiration and ventilation. There will be many pores in many places on the fabric. This material can achieve good perspiration, quick drying and air permeability. Everyone knows that cotton is more breathable than polyester, and it is not easy to absorb sweat. It is very uncomfortable when it is wet. Therefore, the sportswear is mainly polyester, but pure polyester is airtight and sultry, so many breathable meshes are added to the clothes, especially the back. Sweat oozes from the mesh and dries easily during exercise.
