However, if you have an athletic build, the larger size may be appropriate. For tops, please choose the larger size. This is the successor design to the classic A400, the king of the SKINS brand, and follows its patterns, making it a must-have item for compression wear enthusiasts. It is designed with 8-10 panels. (A larger number of panels leads to appropriate compression and a better fit to the body) The material used is nylon 6, which is lightweight and highly elastic. The moderate compression strength allows for use in daily life (including standing work and long-distance travel). The logo is silver.
